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%.
