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.

Recovery of Gold by Precipitation with Zinc. This sample has 10-20 grams of Zinc, which theoretically can precipitate 0.7 grams of gold from pregnant solution refining or aqua regia acid after use

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 7 ай бұрын

@@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.

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.
