Solved One stage in the extraction of gold from rocks
One stage in the extraction of gold from rocks involves dissolving the metal from the rock with a basic solution of sodium cyanide that has been thoroughly aerated. This stage results in the formation of soluble Au(CN)_2^- ions. The next stage is to reduce gold to the metal by the addition of zinc dust, forming Zn(CN)_4^2-.
