Your last video on Alaskan gold yielded approx the same percentage after refining. The lesson i am learning is to not pay spot price for this type of gold until it has been refined.
I'm the 777th like. Pretty lucky! I enjoy your videos and have learned a lot from you, though I have never tried what you do, nor would I unless I had the right facilities. It's so much fun watching you get precious metals from these experiments. Thanks for all you do.
I’ve gotten placier gold from all over the U.S. , and every time I refine I have the same issue you ran into,, with the odd colored chloride forming,, then I decided one day to put it in nitric first ,,it took a while the first time but after the pretreatment I didn’t have the annoying chloride to deal with,, so the next time I did it,, I made a roller to run the gold dust through first to smash it all into little flat flakes,when I did the pretreatment that time it took 30 minutes to remove all other metals, and when I hit with aqua regea it took less than One Hour an was in solution,, rolling it first made ALL the difference in the world,, I HOPE THIS HELPS YOU OUT FOR THE NEXT TIME,,, nice video Sir
Hello Mrs and Mr sreetips. I talks from my heart now... This canal could be on nasjonal tv...I get that feeling every time i see a clip from you🌹. That have generated more money in the hobby refining. So good is this canal. Nothing is impossible in his name🙏 Thank you so muth for 2022,and i wish you, and your famely a great.. great 2023. Happy new year 🎉🇺🇲 to you, and everybody who follow this canal🎉. God bless all of you. Arne
excellent video, however, i was suprised at the 50% yield after the second extraction. I was a chemistry major 30 years ago, so I need to brush up on my inorganic chem- that said have you discussed the possibility the another constituent in the placer gold complexed with either free Au or Au+ in solution , reducing the yield? That greenish tinge in the first extraction (Fe++) had me confused, because normally, well panned gold will eliminate metallic iron and FeOx from the concentrate. I would love to see an XRF or Mass Spec curve. Ill have to research any available USGS archival data. I am certain someone has extensively cataloged the exact makeup of Au throughout the Alaska region. That 50% number needs some serious investigation.
That was an interesting thing to see and hear. I had no idea metals could recombine so quickly. Is that a property inherent to precious metals? Great video. Thanks for sharing
More than 50% gold by weight(if just barely), the guy doing the panning did a really good job. Mine operators would completely lose their minds for those numbers.
Lots of dirt, sand and metal contamination. Lesson, next time you see 1000 oz on Gold Rush = not. By the time they refine it, that weight can go way down. Gold is a cold weld matierial, just pressure can make it bond into nugets, with lots of crap mixed in.
Hello Sreetips, since my first comment I have conducted 4 tests one with 1g of 9k gold, 3 with 1 g each of alluvial gold dust (about 89 - 94 % fine) without inquartation . 1 g of Au in 10 mls of 32% hcl adding 1.2 g of kno3. Placed on heat, this first batch dissolved most of Au, poured off and 2. batch of the same dissolved the rest. Cooled down I added 4x of dest. water to combined solutions, That dropped Ag out of solution, I filtered that off, having clear amber solution, dropped gold with 1 - 1.5 g of smb followed by rinsing ,boiling in d. water, hcl and the same, ending with 0.88 -0.93 g of gold and very small bead of ag 0.04 -0.06 g .I had to be very careful working with such small amounts.I got a hint from Shor international , they use subzero, but it must be some form of nitrate, my knowledge of chemistry is limited, but I ended up with 4 nice beads, in case of 9k gold it is 0.35g out of 1 g . If You have time cast Your critical eye at it and let me know what You think of it, regards George
I have to thank You for so quick response, I only described process I followed, learning from Your videos and other info I got online. When You go to Shor international they offer kits for refining gold with substitude they call subzero in lieu of HNO3.Looking into it I meant You trying the same process using 9 k gold instead of placer gold.With beads I ended up with, I cannot prove what purity they have.Providing I haveYour E-mail address I could send You picture of those beads, regards grateful George from Down Under.
Hello Sreetips, I have to explain myself. That first test with 9 k done some time ago was done by inquarting, resulting in o.35 bead of Au, silver was recovered as well.Next 2 tests with 1g of alluvial Au of over 90% purity gold was dissolved in Hcl and kno3, to coninue when reaction stopped I was adding 6% h202 ,few mls .However this precipitated silver chloride out of solution and was dissolved again, until all Au dissolved. Then adding 4x water would drop silver chloride, then filtered and continued with smb to drop au.Last test I did I did not want to add anything and dissoled au in 2 lots of hcl and kno3.That is full descriptionof those tests.I am going to quote from text:Low silver content(less than 8%)will not create passivation of the metal and therefore can be dissoled directly in A.R.High silver content will form layer of insoluble silver protecting gold from A.R.Best news I managed to order nitric acid from Sydney chem. comp.Might interest You 2 x 500ml bottles, A $ 17.50 each + 10 % tax ,shipping 280 km A$ 37.50. Say $75 . And that is 68% hno3. Thank You for Your patience, thank You for All Your videos, one never stops learning, regards George
George, sounds like your experiments are paying off. I am still refining my refining processes. You'll see what I mean with my next video upload. Inquarting with silver (clean copper or brass will work also, but will require more nitric) then parting with nitric acid completely eliminates passivation. Silver chloride is slightly soluble in water, more so in hot water. This is why your gold solution will appear crystal clear, then turn cloudy if you cool it down or add water to it. I always add ice before filtering to force any silver chloride that is in solution with my gold to come out of solution so it can be filtered out. If I want high purity then I will usually do multiple refinings of the same batch until I achieve an absolutely clear and bright orange gold solution. Large amounts of silver chloride won't redissolve. The only solvent that I know of that will dissolve silver chloride is hot ammonia.
@@sreetips , thank You for Your early descriptive reply,now with available hno3,I am going to inquart with silver and process is going to be without guesses.Looking forward to see Your new video, regards grateful George
Love the videos and I tend to jump all over them and go from 2 years ago to 2 weeks ago so I was wondering if the reason you didn’t inquart this was because of how fine it was or if there was another reason. I know I have seen your other videos with natural gold that you did but that seemed like larger pieces than this dust.
Interesting stuff as always. One question though, how come you melted it into shot instead of a gold button as I've seen you do in other videos? Take care and I'll see ya in the next video.
I would have loved to see this stop at the point where there was gold balls formed. How strange… Have you ever seen that before? I wonder how dense they were.
You said it was a pleasure to do this refine, I'll say it was a pleasure to watch!! One thing I noticed is the difference in the yield from this placer gold and the other/others. If my memory serves correctly you got close to 80% yield from an earlier video refining placer gold and this one was closer to 55%. Is that the way placer gold is, it just varies in purity depending on what other metals it might be mixed with?? Thanks for a GREAT VIDEO SREETIPS!!!!
Placer gold is gold that occurs naturally. It was formed at the center of super massive stars that collapsed and went super nova. It is under these conditions of extreme pressure and temperature that enough force exists to force protons to fuse together and make new elements from other, less heavy elements. Then the elements get scattered in space and end up on our planet as gold. But placer is not pure. It's mixed with other metals. So each piece of placer gold, depending on where it was found, will contain varying amounts of gold. From 75% to 90% has been my experience. But none it it is ever high purity. The only way to get that is to refine it. Plus these experiments were done as I was trying to find a way to refine the placer without using any nitric acid. It can be tough to get for some folks. So my technique may have affected the yield. The best way to refine placer is to melt into a button, stirring with a graphite rod to ensure complete alloy. Then inquart with silver or copper and refine as usual.
Kinda....Our planet was formed through accretion, as these paticles the size of neutrinos to the size of mountain ranges collide they, in millions of years form a planet such as earth. While these fragments of star material are formimg into a planet they naturally have these elements infused. These elements also arrive at earth by the way of comets, meteors and the like. Although, in a very small percentage compared to when the earth was in its forming stages. Alot of people believe that all the gold found on earth was delivered by asteroids and meteors after the earth was formed. Only a very small amount is delivered in this fashion since the formation of the moon. The moon being a shield for earth. It takes a certain capacity to see these truths and there are many different things that try to hide these truths religion being one and the life expectancy of humans being another. Conjecture? I think not!
That was cool. I still have 104 grams of placer gold from the Yukon. I’m gonna try this procedure That came out extremely pure it looked just like the 24k 999 jewelers shot you can buy to make jewelry with
Would Sodium Chlorinate /Sodium Meta Bisulfate drain clearner work good to precipitate the Gold out of the Aqua Regia? I noticed it listed together in the ingredients.
If there are any dissolved metals in with the gold powder (unlikely as indicated by the colorless liquid on the gold after filtering) then water may not have the ability to completely rinse the gold powder free of this contamination. Hydrochloric acid is far better at rinsing metals in solution from the gold powder. Plus it doesn't hurt a thing. A possible benefit with zero consequences. Same thing with adding sulfuric acid before filtering. Small effort and low cost step that could produce a benefit. Precautionary.
I'm surprised that you didn't enquart your placer material as the fineness from Juneau AK area are about 772 to 827% U.S. Dept of the Interior Bulletin 910-c
Don't know if you got your answer. But it's the same stuff as his more recent videos he shows the jug of it and you can see. Don't quote me but I think it's 68% I might be thinking the other acid he used 🤔
I wonder if "Ray" was disappointed with a purity of about 55 % or if this corresponds with the normal value he sells the Juneau gold for. I have watched his videos on collecting it in the tidal mud flats up there and it looks like fun but even for placer this percentage is low without some other precious metal alloyed with the gold.
The spot on his claim may have had a spot contaminated by Iron Pyrite, which would explain both the Iron in solution and him possibly thinking he had a full troy ounce of color due to Pyrite's color, especially if fine grained.
Hello Sreetips,my name is George, half lifetime gold fossicker and hobby jeweller.I am getting flood gold dust, I would like to refine.It assays around 90%.I have only remnants of conc. nitric and sulphuric left,that I could buy until 2000 over the counter,but not now .HCL is available 32 %.I used to buy even hydrofluoric 32 % in 500 mls bottles to dissolve quartz from nuggets. Not any more.I have seen lots of Your videos and I like Your systematic safe style of work.I would like to know a way of refining that alluvial gold dust without nitric acid. I could use KNO3 ,How to separate silver? I am used to work with acids,. I would be very grateful ,if You could help , regards George
George, I wish I could offer you some help, but I don't have any experience refining gold dust with no nitric acid. I've refiner jeweler's dust but the first step after incineration is to use nitric acid to remove silver. Sorry I couldn't be more helpful.
I thought it was necessary to denox with sulfamic acid or urea before dropping the Au with SMB?? How are you able to skip this step? I may have found my answer... you boiled off the excess Nitric! Correct?
I used incremental nitric dosing: adding just the right amount of nitric to just dissolve the gold. If done correctly then there’s no need to denox excess nitric, because there won’t be any to remove. A small amount of excess nitric is not a problem. Just add a little more SMB until fumes stop forming.
I am uploading a suplemental video to this one as I write this. In it I recover some more gold from the residue that was left over from this refining. It was hidden from view, and I acted on a hunch, from previous experience, and got some more gold from the waste.
Great Video, Thanks. I was getting ready to Bitch until I saw the add date. Thats why I havent seen this. Could have used this months ago. I was told keep temp. around 80-90, I just went into shop and cranked it up. I do believe my stuff look's the same. Now could you do a video on gold from sulfide's...Haha Thanks again.
I usually don't boil the solution because gold can leave the vessel in the form of tiny droplets. Be sure to keep it covered. Take a look at the suplemental video I made on the residue, mine still had some gold in it.
I just got done watching it. Another great one, thank's. Temp was running 130-140 last I checked. But bubbling like it's boiling. Trying copper in another to precip. the gold out. Having problem's with SmB dropping. You said in supplemental vid. about gold going into acid then back into a solid. Im wondering, this also. Gona try sulfuric. Plz keep video's coming. I see you volunteered to go to Nevada, heck I will pay your airfare to here,mexico. haha
East side of Sierra mountain range, hour south east of Durango,hour north west of Fresnillo and 15 miles east of Sombrerete. Kind of in center of a triangle of the 3 largest gold mines on the same mountain.
I know it must be hard work, but finding gold from the ground must be a nice way to get it. I get mine from people who want to sell their scrap. I pay 80% of spot. So I get to keep 20%. I'm hanging on to all my gold right now. I see it going to $5k per troy ounce one day. Once people realize that our money is fake. 8 out of 10 people believe that the $USD is still backed by gold. We humans are so easily deceived.
I have to review what you did here. You filtered the solution that you dropped with the SMB. A bunch of iron was left behind in the filter. Then you rinsed the filter contents with HCl. Iron should dissolve quite readily in HCl, which means (at least as far as I saw) that you put the iron right back into the gold solution. That part I didn't understand.
I had iron "in solution" with the gold powder. The gold dropped out as metallic gold with the SMB. The iron was left dissolved in solution because SMB will only precipitate the gold and not the iron.. After pouring the gold powder into the filter, it was saturated with the iron solution. Then I poured hydrochloric acid on the gold powder in the filter to rinse the iron solution off of the gold powder. Hydrochloric acid works much better at rinsing dissolved iron from the gold powder than water.
I don't think that an acid test will give accurate results to three nines. They use an XRF gun to "shoot" the gold and it gives a read out of the gold content and the impurities.
After refining hundreds of ounces of gold over the last nines years, I can tell purity by the appearance of the surface of the bar. I've probably refined around five hundred troy ounces of gold!
I came across a how it works video where they take all of the metals from electronic scrap "gold, silver, copper" and melt them down together into plates and then use the plates in an electrolysis process that separates the metals into pure copper, and then in a separate bath they put in a steel plate to attract the silver and once that's out the gold is all that's left and they melt it down. could you do a complete walk through on how to go about this as well as its pros and cons? this is the link to the video just in case you were curious as to where I saw it. ps. can the same process be used with palladium and platinum? Tanks! :) ua-cam.com/video/zU62hh3DBfg/v-deo.html
salve signor sreetips ma oro 24 carati con acido sparisce lo sa vero perché l'oro e debole ci deve farà una legha di palladio e plarino per io ho preso oro 24 carati offato una striscia gialla e de sparita lo sa vero salve
Only about 18k or so. Placer gold is never pure gold. The folks who sell it on eBay can charge, and get, 110% of spot because people think that it's pure gold.
Really rich placer is ~22k. Most is under 20. The richest I've personally seen was about 88 percent which is about 21k and that was from Australia. Of course, your mileage will differ.
Your last video on Alaskan gold yielded approx the same percentage after refining. The lesson i am learning is to not pay spot price for this type of gold until it has been refined.

excellent video, however, i was suprised at the 50% yield after the second extraction.

Another GREAT video. I knew nothing about refining those. And now I know a little. Seems to be the the regular refining methods. Thank you

Thank you!
nice I knew a Ray Austin from Juneau great video thinking about trying this with my gold.

YOU ARE THE BEST ...... THANK YOU
That was an interesting thing to see and hear. I had no idea metals could recombine so quickly. Is that a property inherent to precious metals?
Great video. Thanks for sharing
More than 50% gold by weight(if just barely), the guy doing the panning did a really good job. Mine operators would completely lose their minds for those numbers.
What was in that second little tube you had on your desk with the tube of original gold?
Pretty good amount of fines
Lots of dirt, sand and metal contamination. Lesson, next time you see 1000 oz on Gold Rush = not. By the time they refine it, that weight can go way down. Gold is a cold weld matierial, just pressure can make it bond into nugets, with lots of crap mixed in.

Best sir
That was cool. I still have 104 grams of placer gold from the Yukon. I’m gonna try this procedure
That came out extremely pure it looked just like the 24k 999 jewelers shot you can buy to make jewelry with
in the UK we call the 'Spot Plate' a 'Dimple Tile' , fascinating I know - Judith M 2023
I like dimple tile
Would Sodium Chlorinate /Sodium Meta Bisulfate drain clearner work good to precipitate the Gold out of the Aqua Regia? I noticed it listed together in the ingredients.
I’ve never used sodium chlorinate or sodium meta bisulfate in any of my processes.
Was that Silver Chloride that formed the gold into balls with your initial HCL treatment?
I don't know. I've never seem that before but it was very amusing to watch them dance like that.
Why do you rinse the filter paper with the gold in the last step with HCl ? Isn't simple water enough ?
If there are any dissolved metals in with the gold powder (unlikely as indicated by the colorless liquid on the gold after filtering) then water may not have the ability to completely rinse the gold powder free of this contamination. Hydrochloric acid is far better at rinsing metals in solution from the gold powder. Plus it doesn't hurt a thing. A possible benefit with zero consequences. Same thing with adding sulfuric acid before filtering. Small effort and low cost step that could produce a benefit. Precautionary.
Sreetips, why acids react more vigorously when hot?
I'm not quite sure, just be aware that they do and use caution when adding acids to hot solutions.
Higher temperatures increase the amount of particles that reach activation energy when colliding.
Do you think, if you followed his process that you would have yielded a larger amount out of it? More weight?
Searching for a way to do this without nitric.
I'm surprised that you didn't enquart your placer material as the fineness from Juneau AK area are about 772 to 827% U.S. Dept of the Interior Bulletin 910-c
827%?
82.7% assayed fineness/purity@@PaulBrown-uj5le
you did it right pal
What is the concentrate percentage on the nitric acid used in this video
Don't know if you got your answer. But it's the same stuff as his more recent videos he shows the jug of it and you can see. Don't quote me but I think it's 68% I might be thinking the other acid he used 🤔
Started out with 31.1 and ended up with 16.9 grams. is Alaskan gold about 58% pure from the ground.
Sounds about right, but some of the gold went into my waste container - I recover it later.
I wonder if "Ray" was disappointed with a purity of about 55 % or if this corresponds with the normal value he sells the Juneau gold for. I have watched his videos on collecting it in the tidal mud flats up there and it looks like fun but even for placer this percentage is low without some other precious metal alloyed with the gold.
The spot on his claim may have had a spot contaminated by Iron Pyrite, which would explain both the Iron in solution and him possibly thinking he had a full troy ounce of color due to Pyrite's color, especially if fine grained.
Placer gold contains sulfides and quartz and other minerals you may not see when dealing with jewelry thats had it all removed
I’ll be doing a video with some Alaskan placer real soon. Those impurities will vanish under the torch.

@@sreetips thank You for Your early reply, I will try to source some from someone not needing it any more regards George
Stamp out a 2020 golden coin for yourself mate. You deserve golden teeth !
I think I would probably stir it a lot more
Thanks sir.. 😆😆😆
I thought you were gonna let it cool into one bead
I thought it was necessary to denox with sulfamic acid or urea before dropping the Au with SMB?? How are you able to skip this step? I may have found my answer... you boiled off the excess Nitric! Correct?
I used incremental nitric dosing: adding just the right amount of nitric to just dissolve the gold. If done correctly then there’s no need to denox excess nitric, because there won’t be any to remove. A small amount of excess nitric is not a problem. Just add a little more SMB until fumes stop forming.
I like the placer gold vids!
Very nice result, but not a very high yield.
I am uploading a suplemental video to this one as I write this. In it I recover some more gold from the residue that was left over from this refining. It was hidden from view, and I acted on a hunch, from previous experience, and got some more gold from the waste.
Sounds like a bit of gold intuition. :)
That was a great yield. The placer was 50% junk. Now it.s 16.9 pure gold.
Hi may I ask what filter paper do you use
Number 2 medium flow
Thank you is that 2 Micron
I don't know the micron value. I use three types, fast 01, medium 02, slow 03.
Great Video, Thanks. I was getting ready to Bitch until I saw the add date. Thats why I havent seen this. Could have used this months ago. I was told keep temp. around 80-90, I just went into shop and cranked it up. I do believe my stuff look's the same. Now could you do a video on gold from sulfide's...Haha Thanks again.
I usually don't boil the solution because gold can leave the vessel in the form of tiny droplets. Be sure to keep it covered. Take a look at the suplemental video I made on the residue, mine still had some gold in it.
I just got done watching it. Another great one, thank's. Temp was running 130-140 last I checked. But bubbling like it's boiling. Trying copper in another to precip. the gold out. Having problem's with SmB dropping. You said in supplemental vid. about gold going into acid then back into a solid. Im wondering, this also. Gona try sulfuric. Plz keep video's coming. I see you volunteered to go to Nevada, heck I will pay your airfare to here,mexico. haha
what part of mexica?
East side of Sierra mountain range, hour south east of Durango,hour north west of Fresnillo and 15 miles east of Sombrerete. Kind of in center of a triangle of the 3 largest gold mines on the same mountain.
I know it must be hard work, but finding gold from the ground must be a nice way to get it. I get mine from people who want to sell their scrap. I pay 80% of spot. So I get to keep 20%. I'm hanging on to all my gold right now. I see it going to $5k per troy ounce one day. Once people realize that our money is fake. 8 out of 10 people believe that the $USD is still backed by gold. We humans are so easily deceived.
I heard that CALIFORNIA Gold had a much higher percentage.
#3 last one
27:17 NICE!
I think you can now say your process yields .9999 fine.
I have to review what you did here. You filtered the solution that you dropped with the SMB. A bunch of iron was left behind in the filter. Then you rinsed the filter contents with HCl. Iron should dissolve quite readily in HCl, which means (at least as far as I saw) that you put the iron right back into the gold solution. That part I didn't understand.
I had iron "in solution" with the gold powder. The gold dropped out as metallic gold with the SMB. The iron was left dissolved in solution because SMB will only precipitate the gold and not the iron.. After pouring the gold powder into the filter, it was saturated with the iron solution. Then I poured hydrochloric acid on the gold powder in the filter to rinse the iron solution off of the gold powder. Hydrochloric acid works much better at rinsing dissolved iron from the gold powder than water.
Just watched your supplemental video on this but this is still a low percentage of pure gold. But as is said you get what you get.
Lots of sulfides?
I’m not sure about sulfides
how much SMB do you put?
As much as it takes to drop all the gold
@@sreetips thank you, how do you know when is all going to drop because the reaction is a bit delayed?
No, I can tell by the color of the solution as I add the SMB. For inexperienced probably best to test with stannous.
So Franks placer gold is coming out to about 53% pure.
I think it was closer to 75%
Is this Ray from gps ?
Not sure
How do you know the purity do you have extra gun
The big refiner has a gun. The assay comes back three nines every time.
I guess you got the refining down to a science.
I guess you can also test with 24 k asid
I don't think that an acid test will give accurate results to three nines. They use an XRF gun to "shoot" the gold and it gives a read out of the gold content and the impurities.
After refining hundreds of ounces of gold over the last nines years, I can tell purity by the appearance of the surface of the bar. I've probably refined around five hundred troy ounces of gold!
✔
ok
And I thought you would have done inquartation... I know it is spelled wrong.
High carat gold doesn't need to be inquarted
Caleb Bennington , your spelling is fine
I would have inquarted if it were mine. The experiment was to do it with out using lots of nitric acid.
I came across a how it works video where they take all of the metals from electronic scrap "gold, silver, copper" and melt them down together into plates and then use the plates in an electrolysis process that separates the metals into pure copper, and then in a separate bath they put in a steel plate to attract the silver and once that's out the gold is all that's left and they melt it down. could you do a complete walk through on how to go about this as well as its pros and cons? this is the link to the video just in case you were curious as to where I saw it.
ps. can the same process be used with palladium and platinum?
Tanks! :)

Sorry, I don't have any experience with this level of computer scrap. They are processing a dumpster full of scrap. I work with 4 liter beakers.
sreetips i wonder what the electrolyte is that they are using that enables them to do it this way.
salve signor sreetips ma oro 24 carati con acido sparisce lo sa vero perché l'oro e debole ci deve farà una legha di palladio e plarino per io ho preso oro 24 carati offato una striscia gialla e de sparita lo sa vero salve
gli articoli placcati in oro sono meglio lavorati in una cella di stripping di acido solforico
Im don’t anderstand you Beginn to 3,gr
Wow. That’s really low grade gold. I’m surprised.
Only about 18k or so. Placer gold is never pure gold. The folks who sell it on eBay can charge, and get, 110% of spot because people think that it's pure gold.
Really rich placer is ~22k. Most is under 20. The richest I've personally seen was about 88 percent which is about 21k and that was from Australia. Of course, your mileage will differ.
hahaha ... little balls apearing...
Where is the silver that was in that gold?
Recovered it.
