Do Your Buckets Of Black Sands Have Value? Assay For Gold At Home To Find Out!
Вставка
- Опубліковано 6 кві 2020
- This method is easy to do and will determine if there is any gold or silver in your buckets of black sands/sulfides you have laying around. This could be free gold that is hard to recover by gold panning or gold that is locked up in sulfides or iron pyrite. First roast the black sands to oxidize any sulfides, then smelt to recover any gold or silver. Next process is cupelling the lead collector metal to reveal the gold and silver collected from the smelt. Once the amount of gold is determined then it is easy to tell if there is enough value to save those buckets!

Are you a miner? No.
Do you have a refinery? No
Do you want to watch this video at 3am? Sure why not.
Lot of iron in the blue bloods? @everyone is mine crafter. Kitchen witches.
Literally 2:57am lol
Get a cast iron flat top griddle, maybe that’d hold up better.
I am watching it on 10:50
Not the video rhe time :v
For me the piss off value to the wife is more valuable than any precious metal recovery.
yup. two days in the shop playin with fire
Bwahahaha
Really good job on some of those shots, especially the cooling flux, it looks like you can see the convection cells moving around
I’m surprised that $1 cookie sheet lasted as long as it did. 😳
We are too! Thanks for watching our video!
@@mbmmllc 60 gr Gold in 1 ton of black sand it is very big persent and absolutely impossible !!!!!
Seriously!! When I saw it hadn’t buckled and was red in color I was impressed!! I had figured he would have had to go to the cast iron.
Right! I was expecting it to warp and be scrap after a few minutes 😂
😄
This was really helpful Jason. Time to ditch it. One thing I have learned is black sands works really well as step one in a rock tumbler to smooth the sharp edges on rocks. So one could sell the black sands as step one tumbling grit 😅
3:37 Had to laugh there. As you were cooking it I was thinking "How does he stop the tray from being eaten?"
Now I know :D
I have much the same results from hard rock sulphide ore, not a lot of $ left in there, just put it through the mill again for re-grind.
Always worth checking to see what your recovery is, goes to show how bloody good your table works! Enjoy your vids, cheers!
Great point! Thanks for watching!
Love your no bullshit approach for giving information in video form!
Thanks
Was totally expecting the cookie sheet to "springwarp" from the heat, throwing the sand everwhere!
I remember back in the day, miners would also sell their black sand, they wouldn't get much, but it did add to the year end total.
I never really got the cupel theory until just now very well at least that i could understand explained so thank you for that
plus on ads I hope you get a nice payout from this one that is 41:07 long I'll just let it run out
Maybe you could make a "cookie sheet" out of the same steel that you made the cone mold from. Also, if the economy really does tank as bad as some people think it could you may find yourself out on your driveway with a broom and dustpan.
haha, agreed
Old griddle will do
Cost more in paying for the energy to process it than you'd get from the metals.
@zamistro Hahahahah !!! That's a really cool one !!
So exactly as it has 😂
The only trick may be if theres a way to separate out the gold bearing minerals more such as flotation or magnetic, or static, etc. If you could reduce those 38kg into 500g and maintain a large majority of the gold without expending too much money, it could be worth stockpiling until you have enough to process.
You and the guy who mines platinum from the freeway should get together and have a beer.
Dude MBMM and Cody’slab is the best combo
I wonder does the states dot refine the dirt and dust from the freeway sweepers?
@@blueridgeocean it isn't cost effective, you have to hire people, and collection machines, and then processing machines as well.
Although, right now there is a platinum/palladium shortage, so it could be worth it, eventually.
Codyslab and The Cerro Gordo guy should make a video together extracting some silver from the mines!
How dare you call Cody "that guy" I'm calling the feds
The tailings make great roadway material, fines help hold a road together.
I would like to get into this at some point, and I will have the best gravel road on earth.
Thanks for this video, the cooling process was fascinating to watch!
Glad you enjoyed it!
Gold leaves the black sand during roasting via aerosol. Yep.Thank you so much for these videos.Its just pure awesome!
tell me more how did you know?
@@dogodogo5891 I could look up some studies if you like.I looked into various reports.
In one instance , it was when the miner, tore down the flue or teared down a wall, they would find gold fuse in the material after years.
I haven't tried watching this sober, but this was great, well done and thank you!
just dont try DOING THIS with a buzz on.😂
Well you could have just done .06x38 to get your 2.28 figure, converting both figures up to tons was just extra steps.
Those patterns as the slag cools is pretty cool to watch.
cast iron griddle got a few on sale from Walmart . Was not that good till i took a grinder to them. To smooth them out right. Season it and it work great now.
I suspect someone has already suggested amongst all the other comments but, I would use an old cast iron barbecue plate instead of the cookie tray for any future trials. Large surface area and as durable as a pan.
When the metal is cooling you can see the molecular shapes with all those lines that’s awesome
I make the same noises your son does when i see metal being poured. Something so satisfying about it.
Haha, he had a good time, mostly played iPad in the truck though :)
The "boo boo" made the video more educational. Thanks for keeping that in. Great stuff, Jason.
Glad you enjoyed it
@@mbmmllc I did also notice a lot of (admittedly) small bubbling on your first pour .
Is that normal? Could the matt be caused by the smelt just needed more time to settle down and complete any reactions before you did pour?
Thanks Jason for sharing the experience.
Well that proved your recovery methods are doing very well in getting the gold.
This video helped answer many questions I had, thank you. 👊
Have you thought of using a black iron wok instead of the cookie tray or cast iron pan. You can move the "sand" by flicking it, kind of like stir frying & woks (black iron) tend to handle heat better then cookie trays.
"Hope you learned something."
Lol! I learned something, alright. Thanks.
everyone always asks "What are you going to do with that?", my response, "What are you, my wife?!?!" My hording is aluminum, brass and copper ingots, but same conversation across the board it looks like!
Yep, why don't they just leave us alone??
@@mbmmllc subbed for this comment lol
i got poor returns on my ingots.
just subbed and thumbs - up, that sounds like the gold off our beaches that are in the black sands, be strong, be safe, and be blessed
Very interesting and instructive video. If the assay said there was enough gold to warrant more processing, would you use a shaker table, or something like what you showed here to extract it?
Great video, thanks for going through all that effort.
Glad you enjoyed it
Love these videos! I no longer have my jaw, but I still keep up with you. Maybe some day.
Sweet vid, lovely to hear yeah kid getting excited about first pour! Future smelter in the making right there :D
You got great content your the Real Parker Schnebly man way better than gold rush, cause it’s all genuine!
And keeping the Mrs. happy is what it is all about..lol. stay safe. Stay healthy. Hope 2022 is a great year for you! 🍾🍾🎊🎉
For the amount of energy and work put into your efforts the profit margin was too low to perform this task often. I did like the video it was very informative. Thank you for your efforts. It was enough for a sub!
Thanks, Yes this was just an example, but you can imagine if your black sands have more gold it would be worth it :)
I was told when roasting black sands to add salt to the mix---Is this a-go with this process? Thanks for the advise. DAvid out
Cheapest, yet effective forge I've ever seen.
Thank you so much for sharing that was very educational. Something I don't understand very well is after you have the lead with the gold and silver in it and you heat it up again how are you removing the lead, are you using a bone ash crucible to suck the lead out? Maybe you can explain that a little for all us amateurs, thank you so much for your time in answering this question.
That probably answers alot of questions!
Have a Great Day!!
7:27 ... "*GASP* It's ... it's EWUPTING!!!"
That's awesome, cute kid! Thank you for the info Mt. Baker!
Good job Jason, this was cool to watch.
always learn from your vids, rock on brother man
after roasting, those cons would have been a good run for some aqua-regia...grind them down to 1000 mesh and soak em and then you know for sure what you got.
Black sand makes great traction grit. And, you can recover it with a magnet and reuse indefinitely.
I like how it spontaneously forms veins.
That cookie sheet was still more valuable than the gold content... ^^
Absolutely
The ad revenue is still more valuable than the cookie sheet, fuel costs and gold recovered all together
@@blueridgeocean Probably... ;)
You could substitute the aluminum cookie sheet for a cast iron griddle
Good idea, thx
Very cool gives me something to do with my sulphides thanks for the great video.
Glad to help
When you are finished extracting the gold, consider to refine the black sand into artisan quality iron for blacksmith use,
natural magnetite is actually a steel. A steel/gold alloy probably has to get hotter to drop out the gold into the collector metal than you got it. Have you ever shot the slag with the XRF?
so basically AuFe304 or Fe3AuO4 lol that's very strange but very interesting! do you got any references i would like to learn more, thanks!
The easiest way to recover that gold is to wait until you have a ton or more, then set up a small leech field type system and recover the gold that way. It takes way less effort and you recover ALL of the possible gold from those low quality materials. You do it in small batches like that so that it can fit inside of the containment system you build. Granted this is only worth it if you end up with a few tons of that type of material every year from a mining operation, but it would work and be a heck of a lot cheaper to do than to crush it, roast it, and process it in a furnace.
You can use a grilling plate next time, they are built with the same material as a cooking pan and have same surface as a cookie sheet.
Great instructional videes, where do you get the larger graphite molds, seems there is nothing but the smaller ones available.
Looking at the numbers I got to say that it was not cost effective but a good learning video :)
Thanks for explaining some of the science for new viewers.
Glad it was helpful!
Jason is a stud! Love all the videos buddy thank you!
Thanks Jeff!
your theory makes total sense about your collector metal
When it comes to roasting the sulfides would a rotary kiln make sense for that process. The constant tumbling in the drum and heat seems like it might expose it to plenty of oxygen and get the job done quickly.
Your not the only person I fallow on UA-cam who’s kids make a cameo appearance. I think it’s great 😄🍻👍
Was thinking. The blob of iron at the bottom but them mix iron shavings in with the material being smelted. Let it do the same thing you were saying move around on the current with the precious metal as both melts then fall and mix with the blob at the bottom.
You can find a cast iron griddle, then you can have the surface area to work with again.
Always great stuff love watching
Another excellent and informative video. I've learned alot from you. Thank you.
You might see if your scale weighs in grains and do your math with grains when you have sub-gram inputs... and only if you need to be more precise.
Well done.
Thanks for the tip! I have a super accurate scale on order so check that out in up coming vids
I'd try another cookie sheet, but without the nonstick surface. You can find rolled aluminum half-sheet pans for cheap and they don't release carcinogens when heated past 450°.
Do you run your slack to through a ball mill and use it again?
Also what happens to the used cupel? Is there a recycling path for them to get back the lead?
Ur experiment very good bro....
Because remening dust is also valuable.....
we burn off sulfides at 1930 degrees in a crucible and after that without cooling the crucible down or shutting the furnace off we add flux and lead shot(packaged in ashless filter paper(be quick!)). We do this with 10 crucibles at once. We use much lower quantities though(20 gram maximum). But we have analytical scales (0.1mg) to wheigh the silver bead and we have an ICP to measure gold, platina, palladium and rhodium in the silver bead. Also sometimes there is for some reason a lot of Bi in the silver bead, so important to measure that as well. Often the Bi comes from the lead. Because the lead wheight is a lot higher than the silver wheight, even an impurity of 0.01-0.1% adds up when all the lead is absorbed or evaporated.
One one of the GPAA videos a man was giving his processed black sand to a neighbor who wanted it to add iron to her rose garden.
How do you feel about mixing lead shot in through the whole charge distributed evenly?
Your Shaker Table works to good!
I love it!
You'd think any sulfides would roast in the smelt. In fact I'm quite sure one *could* forego with the roasting alltogether if you used enough time and flux. All it does is inhibit the melt until it has fully decomposed and off-gassed. Same with the Na2Co3 in the flux, it needs to decompose and stop bubbling. I would roast it and use Sodium Oxide instead, but perhaps some bubbling is advantageous for stirring.
My hypothesis to what happened is that you had too little flux and/or time. Another hypothesis that I'm leaning more towards is that the Lead got oxidized and that a little Carbon powder would help.
Is there any way to put the settling jig in a centrifuge? Although , spinning molten metal at high speeds sounds super problematic and dangerous, it would probably speed up the separation process and yield more PM.
I love that your kid is there with you.
He thought it was cool!
Do you have the ceramic wool in your furnace rigidized ? or coated with a satinite ?
I once found 1/2 pound of gold in black sands. It was oxidized. Looked like the sand particles. So we started tumbling it with caustic soda, and sure enough. It was a large part of the concentrated waste materials.
But how does it become oxidized I thought gold wouldn't? But I did find that once. We had like two years of that waste saved. We could have just smelted it. But at the time we didn't know.
Please the black sand you are talking about, is it the same black sand use in moulding pots?
Awesome! I put some of my black sand in jars because I thought it looked cool. But the rest will get dumped like you said. Not worth keeping.
Seems to me that you could make a deal with a local cement plant to use their exhaust for roasting sulfides with heat that they're done with.
Great video. Learned a lot. Really appreciate the hard work put into your videos. Thank you.
Glad it was helpful!
and now wifey is happy with the new neckless and no more mud at the entrance :D
Love the re mat without the button. Much better idea. Where do you learn this magic
Do u have a video for extracting rhodium attached to magnetites? I have a huge deposit of magnetites with traces of platinum family metals and rhodium.
We also tried leaching the gold out of it, with pretty much the same results.
When i was drying my gold from a clean up i liked to vent the fumes out the window,didn't like the matalic taste . Probably not realy that good for ya. Sure do miss watching the fine line. Be safe and happy mining no amount of gold is worth getting sick over.
agreed!
love your calculations. I just wish we knew how much energy is being used in propane and electricity in those calculations.
Cool to see this is in my state!
Do you ever do the reverse calculation to find the break even point (cost to recover)?
Sulfides? Just bake it. But to convert to oxides you can also use whats called "piranha solution." Its easy to get a hold of and will oxidise anything. You also cant use a metal container, has to be glass because its already an oxide.
you should cook that iron pyrite in a distillation setup with an agar atmosphere to get some pure silver
I read something years ago about converting the sulphides into chlorides, and being able to get more gold from your black sands, have you ever heard anything about that? It's been a long time since I read that so I don't remember the details.
I wonder how much gold evaparated from so much heat?. But watching this makes me want to go back and cappel some lead silver that i have. It was rich ore but i was leary of all that lead that could being released into my work area. Still good work thanks for sharing
Would an iron chelant with an h2s scavenger speed up your process? Seems to me, in my uneducated opinion, that that should carry away a lot of the junk right away and possibly allow you to skip a lot of work.
so how do you recovery the lead from the copular clay cup.
I am not roasting sulfides. I crush to 100 mesh, wash, and leach w/HCL. The result is a mix of chlorides; gold,silver,and platinum group metals. I put the solution in a crock pot and sweat off the acid I then place the chlorides in AR and precipitate. You get a purer product than fire assay which will need further refining. Are you getting Platinum Group Metals w/the gold sulfides. Won't hurt to check. nice video. Good Luck.
How about a stainless steel "cookie sheet"? Or a large SS steam table pan?
I have around 100 gen 3 4 and 5 I5 dell lap tops i can take all the boards out of them if you wanted to do recycle them they all are working but have cracked screens and stuff
:) , i see many ur vid now about melting the semi cons... i think u really enjoy it now...
Yes, its fun
I'm digging all the videos bro!
Glad you like them!
