Dust is used instead of the zinc shavings formerly employed on account of the large surface area made available. The method is based on the fact that gold and silver are electronegative to zinc and that the following reaction occurs in the precipitation process. KAu (CN)2 + 2KCN + Au + H2O = K2Zn (CN)4 + Au + H + KOH.
Gold and Silver Leaching. For Gold and Silver, the most common leachants used are Na or K cyanides in the presence of oxygen, Thiourea (NH 2.
