  • Gold recovery from Aqua Regia Acid Use zinc powder.‪@MakeGold‬
    Aqua regia is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange (sometimes red) fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum, though not all metals.
    Aqua regia is primarily used to produce chloroauric acid, the electrolyte in the Wohlwill process for refining the highest quality (99.999%) gold.

    What did u do with the bulk sediment before using zinc..it only shows in process the sediment from the sync powder...or is this video only to show how to get back remaining gold sediment left in aqua regia

    Hi there over here in the UK its difficult to get the acids because we had a number of idiots using acids to burn flesh . The UK government made it clear you have to be licensed to use hazardous chemicals and to have the right protective gear visited by health and safety yes that's why it's difficult to extract gold from electronic wastes.

    Some HELPFUL TIPS for you Archimedes : 1 when you finish the hot water wash... rinse all your gold powder out of the beaker into a coffee filter with Borax already in it, and twist tight to ring out any excess water. 2 the powder does not need to be dried out completely . 3 wet sand your crucible bowl with 2000 grit sandpaper smooth...then fire it red hot and add Borax too hot glaze it hard. 4 Now once you have crucible bowl perfect add some more Borax and place the whole twisted coffee filter in and start the firing with propane 1st until it gets blood red hot, then go too acetylene brazing torch *( Not Cutting the cutting one )*because it will not blow the powder gold dust out of the crucible.

    Gold salt is a powerful oxidant, zinc powder a good reductant. Zinc is zerovalent in its metallic powder form, meaning it has 0 charge (not a salt). When mixed with gold salt with a charge of +3 per gold atom, electrons from the zinc powder are transferred to the gold, this reduces the gold iii to gold 0, which is the metallic non-salt form of gold, zinc loses 2 electrons to become a zinc ii salt. In essence, zinc and gold switch places in terms of salt vs metallic form. The optimal molar ratio of zinc powder to soluble gold salt is 3:2

      With that said, I just subscribed to your channel! I have a question, can caustic soda be used to denox aqua Regia. I tried it. Im on day 5 of letting it settle 😳

    • @Glucoperon
      @Glucoperon 9 місяців тому +1

      @@BullProspecting Caustic soda: (Na+ OH-) is not able to be oxidized and thus there is no way to reduce the NOx in solution. If the solution is no longer acidic and at neutral pH, the oxidative species may have decayed by 5 days but no, caustic soda doesnt denox. If you are at neutral pH or even just slightly acid youl have more problems on your hands now. If you add Zinc it will drop the gold from solution slowely but the zinc wont dissolve thanks to no acid so you will have a mess. without a strong acid environment, SMBS won't react with to form SO2 gas which is needed to drop the gold. To neutralize NOx you need something redox active towards the NOx like urea, metabisulfite, or vitamin C. In short. Urea or vit C are to deactivate the solution but not drop gold. They just save you money on zinc and SMBS. Zinc and SMBS are to drop gold out of acid solution but in a large excess they can both deactivate the aqua requa solution AND drop out the gold. So: Au-Auqua Regia --> urea or vitc --->Zinc or SMBS ---> Gold powder. OR. Au-Aqua Regia ---> LOTS of zinc or SMBS----> Gold powder.

  • @10171981
    @10171981 5 років тому +4

    Ummm… so now if you use the zinc powder you have to use MORE nitric acid to separate the zinc from the gold powder instead of just using SMB which then would be your final step to get the gold mud into your coffee filter letting it dry and then melting the powder to make a gold bar.

    • @10171981
      @10171981 5 років тому

      Of course adding SMB AFTER you put in Urea so that it won't keep turning into liquid from due to the remaining nitric acid and hydrochloric acid continuously breaking it back down.

    • @dontbea7237
      @dontbea7237 5 років тому +7

      No what he is saying is smb cant remove 100% gold so after smb recovery he runs a second parsipatant to remove gold lost in solution with the zinc so instead of getting 95% or so hes squeezing out every bit by double extracting the same liquid

    Hello, nitric acid and hydrochloric acid form acid. Does acid dissolve gold?

    • @MakeGold
      @MakeGold  3 місяці тому +1

      Yes, a mixture of nitric acid (HNO3) and hydrochloric acid (HCl) can dissolve gold. This mixture is called aqua regia (Latin for "royal water").
      The chemical process works as follows:
      1) Nitric acid oxidizes the gold to form gold ions (Au+3).
      2) Hydrochloric acid provides chloride ions (Cl-) which react with the gold ions to form a soluble chloroauric acid complex (HAuCl4).
      The overall reaction is:
      Au (solid) + HNO3 (aq) + 4HCl (aq) → HAuCl4 (aq) + NO (g) + 2H2O (l)
      This is one of the few ways to dissolve the relatively inert noble metal gold. Aqua regia is able to do so because of the combination of an oxidizing agent (nitric acid) and a complexing agent (hydrochloric acid providing chloride).
      Individually, neither nitric acid nor hydrochloric acid can effectively dissolve gold on their own. The mixture of the two acids is required for gold dissolution to occur efficiently.
      So in summary, yes the acid mixture formed from nitric acid and hydrochloric acid, known as aqua regia, is indeed able to dissolve and solubilize gold through a redox and complexation process.
