Gold Mining Process Development - Denver Mineral Engineers
Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%.

Gold Processing Plant | Multotec
Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants. Carbon-in-leach (CIL) is a process of cyanidation similar to that of CIP. The difference is that in a CIL plant, carbon is added to the leach tanks so that leaching and adsorption take place in the same tanks.
