Gold Cil/Cip Process
About Gold CIP. Gold CIP is one of the methods of gold extraction by cyanidation. It is a carbon adsorption process of monovalent gold cyanide [KAu (CN)2] after the cyanide leaching of gold-bearing materials. CIP usually applies in flotation gold concentrate, high argillaceous oxidized gold deposit, mercury mixing, and gravity separation tailings.

Cyanide Free Gold Leaching Alternative
Cyanide (CN –) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H 2 O) to form a gold cyanide complex (Na. [Au (CN) 2] ) …
How to Make Cyanide
2CaCN2 + 4H2O = (CN · NH2)2 + 2Ca (OH)2. (2) This, when fused with sodium carbonate and carbon, is largely converted into sodium cyanide: (CN · NH2)2 + Na2CO3 + 2C = 2NaCN + NH3 + N + H + 3CO. A portion of the dicyan-diamide sublimes and polymerizes; this is recovered and re-treated with Na2CO3 in a subsequent operation.
