If you haven't seen Sreetips on YT, he has a ton of refining experience videos - a great teacher. Nice job mate!
Sreetips does another refining by dissolving the gold in Aqua Regia and precipitating it back out prior to melting. I'm not sure if this one is even two 9s fine without the AR bath
Sreetips is very generous with sharing his information just like Jason.
Both are part of my favourite channels.
Jason had mentioned Sreetips in a previous post.
Sreetips is such a good educator that I kept hearing him explaining what Jason was doing, except when Jason didnt "Do" something 🤣 Then I was like "HEY! You forgot to do something!"
I was waiting for the Aqua Regia too, and a proper filtering of the shmutz from the suspended gold.
5000th sreetips comment, yeah, I 🤔 think he may have heard about him😂
When melting the alloy inquart stir with a carbon or quartz stir rod to mix thoroughly. Gives a near perfect alloy every time. Check out the "flame polishing" technique Jason it's what the mints use. Nice mirror finish. Thanks for sharing
Friendly tip Jason;
When using nitric, keep your heat on low, add nitric, and once reaction slows down, then bring the temp up.
There are 2 main things you’re doing that is wasting the nitric.
1: boiling the nitric will cause it to evaporate off/be consumed
2: not using a watch glass (cover) on top of the beaker causes the nitric to burn off easier. When you use a watch glass, not only can you monitor fume production to help you with determining if nitric is working still, you also get a nice distillation effect that causes the nitric acid to pool up into droplets and finally fall back into solution so you “recycle” the nitric and that same acid goes a lot longer.
You can always boil the gold in some nitric if you want to clean it up a bit after the melt, although going straight to agua Regia after the inquarting process is best.
Great work regardless, it’s a bit of a tricky process that takes time to get down to a science :)
Good call seeing as nitric acid boils off and reacts with atmosphere making it less efficient
In my experience HNO3 is such a strange and often frustrating reagent to work with for the DIYer. ive witnessed boiling the hell out of AR just to have my precipitates redissolve when im rinsing? Furthermore i get different colors and types of precipitates with the solution and precipitants being the same each time. I feel like temperature, pressure, and MOST importantly time of the precipitation process has much to do with how well your recovery goes. In conclusion ive had the most sucess when i treat this like cooking with a crock pot..... low & slow is the way to go!
Man, I knew I should have payed attention in chemistry class lol. So cool to see how all the different elements react with each other and burn off what you don't need. Cool video, thank you Jason!
@12:30 sreetips always stirs the molten mixture in the crucible, so that the silver and gold reach a finer degree as inquarted alloy.
Hey Jason! Wow, this is so cool to see how you get all the gold and silver separated. Love seeing the solid chunks and buttons!! Awesome...
Jason I think this is one of my favorite videos. You have perfected your refining techniques and this is the best.
You are a master at this!! Thank you for sharing with us, refining is an amazing process!! I wish you were the new “science” guy that would be required in every high school and college classes!! About time younger generations learned how and where all their gold and silver comes from, especially since it’s in almost every electronic device they utilize on a minute by minute basis!! Thanks Jason!! Keep sharing!⛏😃👍
I think that any High School chemistry class could benefit from seeing this. Nice to have a general overview of a process who's results you are familiar with.
Excellent work Jason! I would love to see you performing the Parkes process and explaining it as you always do, I can definitely use some visual instruction.
Thank you Jason for taking the time, knowledge, and skill teaching us how to!!
I Appreciate!😊
This is great. I found you because I was watching Sreetips videos - and now it's come full circle. Great job.
Lady asked “Why are you watching that?”
Me: “I love learning and watching people learn :) “
Great video Jason!
God bless
Always love watching a process in development.
This is your unique content. I want to see larger scale crushes, liberation and recovery! 10/10!
Jason, this was fascinating. To see the entire process with the added repeats as you determined what was next was incredible and beautiful to see. Quite a dangerous process, handled by an expert. Thank you for sharing it all.
Great video, I think Imma try to understand all this better. You have made it easier to learn the smelting process thanks.
When you were asking about the mix, if you were having an issue with the non-disolving stuff, just add more silver
In terms of silver efficiency, it is better to use the exact right ratio.
In terms of best purity, use an abundance of silver, as a well mixed alloy can still have pockets of high gold density. If you use more silver, it might mean the acid has to eat through 4 molecules of silver instead of 3 per gold molecule, but the more dense pockets will actually clean up better.
I think it means the difference in 99.9 and 99.999% but
When inquiring gold melt at at higher temperature or heat it longer for a more uniform color
You are the first one of these comments that knows the truth.
Except the "inquiring " part .(typo)
I'm starting to enjoy your videos as much as I enjoy Dan Hurds and sreetips. Keep up the good work.
When you inquart you really need to manually mix the metals thoroughly to produce a homogeneous alloy. To finish the refining process you need to dissolve the gold in HCl and Nitric, then filter until the solution is crystal clear, then precipitate. Precipitation can be done by any of several methods, but SMB is the easiest. After precipitation the gold powder needs to be thoroughly washed and then you can melt it in a properly glazed dish.
That was so cool getting that silver cone at the end! Also the gold cleaned up pretty well too!
5:00 This is the only cooking show I like to watch on UA-cam.. 😉👍
your gold look nice finaly, but you may try with aqua regia : muriatic acid + a few ml of nitric to dissolve the gold only, filtered, then precipitating it.
All gold looks nice
Yeah, you always want to put a little excess silver when inquarting. It doesn't hurt the process and compensates if your initial material is higher in gold than estimated.
Alright Jason! Aways love your magic! 💪👍🤠
I wore a half mask most of my career. Check with your supplier or read the directions. My cartridges for acid vapor were only good for 1 day. He told me if I'm using it intermittently I could stretch it to 8 hours of use if I took them off immediately. Taped over both sides and sealed them in a freezer bag with desiccant. Write on the bag how long it was used each time. They suck impurities right out of the air as long as they're exposed. You don't want to end up on oxygen at 50. Change those filters.
I wish I could team up with someone like you to build the machine I've had in concept for fine gold and sand.
Hi Jason, Another great video! Thumbs up! Stay safe. Jim
Jason your works amazing keep it up just love it. I have some interesting ore and projects over in Australia wish I could contact you and share some of my operations.
Id love to send some ore over to have tested. Your shaker tables are unreal well done.
Thanks Jason for sharing this outstanding video with us six stars brother
when i took chem my chem pro said use more than you need if stoke said 150grams use 200. the target is 6k or less so 3k or 4k will work better than 6k which is the limit. more matrix is better than less. good luck jason. great vids i love what you do.
you are one seriously fascinating human being, I would like to hear more about your education and background, I cruised the net and information in this area seems to be limited.
Very beautiful. Beautiful video. Thank you. I am from Syria, your channel is amazing👍
Fascinating. Another informative video. Thanks.
Do you think some smelting ingredients or the collector metal can act like this explanation of inquartation with other elements? Great video as always.
🔥
Great video as always jay👍
Great video. Very educational. Thank you
Wow, nice grade ore. These are the largest buttons I've seen you process
keep boiling in Nitric acid until no fumes, may take 3 to 5 nitric boils
Good seeing you on the tube again
@8:50 I did like that device for pouring the curicible, seemed ta have a much better grip on the crucible as opposed to the grips you normally use that just grabs one edge. Always gives me anxiety watching people grab super heated metal in crucibles by the edge like @ 21:30 haha
Thanks brother... handful of people I come on UA-cam to watch.. don't think I ever heard you swear.. but nicely done again...
If you smash the Cu pipe it works out better than as the pipe just going into the stock pot. Ag and anything else will end up stuck in the pipe becomes a mess to get it back out like that, the thicker you can make the Cu in the form of plate without any openings the better it will cement things out of solution any Au that was taken away by the NO3 in nano particles as a colloidal stuck in suspension will also cement to the Cu and gets caught up in the mess of Ag cementing out and has to be worked again in order to recover it. You did a great job showing how to get started with the process of hydrometallurgy and the mathematical breakdown was easy to understand what you where talking about in the alloys composition. Thank you for the video very useful information and the showing of each deposit type is different and will require you to make some changes as needed for the recovery.
Hello Jason, love your videos. I've been wondering if anyone has tried melting their gold/silver alloy with lead, then add zinc to gather the silver in the scum that forms on top of molten lead. It seams to me it could purify gold from silver.
Me too! Would love to see the Parkes process in details
So cool there is so much to learn about metalurgy.
You should always stir your Alloys with a graphite rod
Love seeing that shaker table run
I just love watching you smelt
If you were to make a vortex in the water bucket with a paddle and drill before corn flakeing would it make a difference in the corn flakes?
You need to mix the silver alloy with the cold to get it consistent , also you don’t have to use silver, you could also use copper if you don’t care to recover the metal after the nitric boils
Did not see if you stirred , maybe the inconsistent color ?
Thanks again
Hi Jason, could you do a video with the shaker table or your mobile hard rock process unit showing recovery of silver in it, so I can see the color of it coming from hard rock. Okay second question….will silver appear tarnished black after roasting hard rock sulphide concentrates???
Wow that was a huge cone! Nice. Do you sell the smaller cone you you use a lot? I was looking for it in your store but do not see it available? Would like to have one of those vs the tiny stuff I see available everywhere.
Silver is a clear when dissolved in acid. So you must do a stannis test to check for silver in solution. Then if negative you go to the next stage.
That was cool Jason!!
Wow. I did not realize what a complicated process it is to seperate precious metals from eachother and from non prescious metals. Holy cow
Thanks for the video.
Is there a specific reason you did the inquartation with silver and not copper?
Love your channel!
i love these vids! More Please 😁
NICE Gold
Have a nice weekend
Yeah Jason I was wondering I've got some or that's very high and silver hornsilver actually and it has gold in it to what's the best way to to refine this
J A video you can make: Take the buttons from glucose test strips and see how many you have to collect to have enough after refining 1 ounce! Would be a nice vid.
I seen the short on the mine with bucket system and where’s the full video of did I miss it
That's a masterclass!
hi you must mix the alloy au/ag in the crucible befor puring for nice homogen materiels
the melt needs a couple of good stirs to ensure a consistent alloy.
Can you not heat the corn flakes to make them soft then hammer them to increase surface area further ?
Great video
Sreetips would stir the alloy to mix it while molten with a graphite rod.
You need to stir your gold and silver mixture with a graphite rod
Do you plan to show us vido of electro-winning the copper from the last video?
Right on Jason bad Brother thanks alot 😊
does iron in ore pervent copper to colloct gold or no ? ❤
I’ve heard before that there is no respirator that will filter out the fumes of nitric acid. That true?
You have to stir the molten gold and silver together to get a uniform mixture.
Do you find these options to be lucrative (seems like a big expensive/time consuming process for about $500 worth of silver). Have you settled on any one process that seems to work better for separating out metals? I am interested in potentially opening an E-waste center which would really take any metal producing or recyclable good but be primarily be focused on E-waste due to the precious metals caontained in them.
I watch a lot of Sreetips. He usually does 75% x 95% of Silver to keep the inquarted shot in pieces in the Nitric boils and not end up with a Gold powder that is hard to spearate from the liquid. He stirs the inquarted Gold with a carbon rod to get a homogenous alloy. He usually does 5 Nitric boils or so. If you add a drip of Hydrochloric to a small amount of Nitric boil you can check for Silver. Silvernitrate will form white SilverChloride that is insoluable. Very sensitive test. Good luck and be carefull!
I am no expert, but my thought is to dissolve the gold in aqua regia then precipitate with SMB, as for the silver, I would really like to show you the chloride process.
Thanks for making this easy for peaple like me I'm no chemist but I love gold I love the hunt
Hallo very nice work
I can't wiat to see you back in your new mine soon. Hope you hit the motherload of a paystreak.
Try pouring the silver onto a water soaked board to increase the surface area for the boil (info gleaned from another channel).
Love the set up the conveyor belt. Less home depot buckets
Hi again Jason, so what if you want to recover the silver out of the acid? Id be interested in recovering both gold and silver out of my mine but I don't really want to go with the nitric acid route.
So satisfying 😊
Yeah, you haven't mixed the liquid gold and silver sufficiently as watching Sreetips, he stirs with a graphite rod and said it needs thorough mixing to make the two homogeneous.
Thank you my brother!
Jason think you might benefit from watching Streetips!
How much do them machine cost I watch a lot of your video and Dan Hurd love you guys! Why burn it off wow lol
Can the cupels be used for anything else after absorbing all the lead?
Melting gold when your crucible has bit the dust
@mbmmllc .. I was remembering something you said about normal borax having water in it vs anhydrous borax .. I wonder if you "bake" the borax beforehand or what it would do as it reminds me of baking Baking soda (Sodium Bicarbonate) to turn it into Sodium carbonate (which is much more alkaline than regular baking soda).. This was a thought as I was having my coffee this morning. or maybe it was another part of the flux I am thinking of.
They call it borax glass when you melt the borax then crush it
@@izysly6924 I was meaning literally baking it in an oven in the kitchen at like 300-350F.. not in the furnace
@ryanac8878 or just hit the borax with a torch until it turns to glass ,then , let it cool ,then, crush it up and use it as your flux.
Yes, the gold and silver should be stirred with a graphite rod to thoroughly mix the alloy.
could have done with a graphite rod and stirred it before purring to make sure the metals have alloyed properly
anybody know how many amps does his electric furnace pulls? am not seeing it in the amazon link or any details, just the watts & volts but the amps are very important
Very cool 👍🏻
Thanks from Australia
when you inquart gold like that you need to stir the liquid metal with a graphite rod or something to get a uniform alloy mixture it looks like the mixture you had is not uniform, but your silver looks quite clean from the get go.
you should make/buy yourself a fumehood to do reactions like this can be dangerous, it is also safer as most fumehoods has a screen that can protect you if some unexpected reactions happend like the solution blowing out of the beaker an flying around the area.
It was great، always gold.
