Using mercury to form an amagum ( dissolve gold in mercury) then heat the mercury to extract the gold by vaporizing the mercury. What is left is the gold. The gold is then melted using a crucible and flux ( boric acid aka borax ). The bead of gold is then dunked in water to cool. Using aquaragia to separate gold involves dissolving, then adding salt and urea. Foam containing silver and other metals is formed and skimmed off the surface. The solution is boiled down and fine gold powder is left. The gold powder is melted using flux in a crucible.
