Gold refining use Aqua regia from Electronic scrap gold
Ғылым және технология
👉 kzread.info Aqua regia is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3.[note 2] 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.

Far better off to place in coffee gringer and reduce them to powder so aqua regia can contact all gild. Wont take as long eitheryou just have to use something finer to filter
Hi Sir, this is good video i will practice and follow the step how to do this. I have one question that can we use the chemical and method the same as this video this to the 18k gold bar 1kg?

It is fashionable to fill everything with sodium hypochlorite and then add hydrochloric acid while chlorine will be released, which will dissolve the gold
Google video and good deskripsition
👍
I think it would be better to use filter paper the let it dry and the put filter in crucible containing gold..the paper will burn off

You can remove nitric acid by vaporizing it and diluting the solution

Put NAOH solution before
I would think you would want to smash tham up so you could recover all the gold
That 0.5g is worth around $30 usd

Gold is money the US $ is just pump up paper promises.
Surprised at the amount of positive comments.. so much loss, way too much SMB, way too much Nitric and your end product is dirty as. Powder should be caramel colour when dry, not near black. Good effort though
Help
