A synthesis of gold (I) cyanide is described which exhibits high yields and does not yield toxic gases (e.g., HCN). Gold (I) cyanide is important as a source of gold for gold plating baths. A synthesis of AuCN that does not involve evolution of toxic gases (e.g., HCN) is highly advantageous because no disposal problem is involved and the procedure is simpler and more straightforward.

Summary of Gold Cyanidation CNLITE Eco-friendly Gold

27/12/2019 1.Gold Cyanidation Principle. Gold Cyanidation is a method in which gold is extracted from gold-bearing ores using aqueous solution of cyanide as solvent, and then gold is extracted from gold-bearing leaching solution. It includes cyanide leaching process and deposition gold extraction process. First, gold in the gold-bearing ore reacts with cyanide to form a complex into the solution, and
