      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 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.

    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

  • @ZoonCrypticon
    @ZoonCrypticon ปีที่แล้ว +5

    @12:30 sreetips always stirs the molten mixture in the crucible, so that the silver and gold reach a finer degree as inquarted alloy.

    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 :)

    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.

Thanks Jason!! Keep sharing!⛏😃👍

    @B0BBYL33J0RD4N ปีที่แล้ว +1

    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

  • @CuttinEJ
    @CuttinEJ ปีที่แล้ว +2

    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.

    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.

    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.

    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!

    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.
