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%.

Where to Buy Cyanide | Order cyanide online - Cyanolabs

Hydrogen cyanide (HCN, also known as prussic acid) is a volatile liquid that boils at 25.6° C (78.1° F). Potassium and sodium cyanide salts are water soluble, whereas mercury, copper, gold, and silver cyanide salts are poorly water soluble. Also, a number of cyanide-containing compounds, known as cyanogens, may release cyanide during metabolism.
