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.
  • @WowplayerMe
    For me the piss off value to the wife is more valuable than any precious metal recovery.
  • @jcpark7242
    I’m surprised that $1 cookie sheet lasted as long as it did. 😳
  • 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 😅
  • @sparky6086
    Was totally expecting the cookie sheet to "springwarp" from the heat, throwing the sand everwhere!
  • @robmckennie4203
    Really good job on some of those shots, especially the cooling flux, it looks like you can see the convection cells moving around
  • @ZE0XE0
    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.
  • @cditzler6313
    I never really got the cupel theory until just now very well at least that i could understand explained so thank you for that
  • When you are finished extracting the gold, consider to refine the black sand into artisan quality iron for blacksmith use,
  • @zamistro
    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.
  • @shalaska989
    Love your no bullshit approach for giving information in video form!
  • 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!
  • @kct9967
    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.
  • @CanadairCL44
    Thanks for this video, the cooling process was fascinating to watch!
