    Cyanide Leaching Mining SGS South Africa

    Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

cyanide leaching africa

cyanide is automatically added to the leach reception tank, with the initial level of the cyanide being controlled by TAC1000 online automatic samples between 0.020% and 0.022% sodium cyanide to dissolve the gold. The underflow from the thickeners is at the appropriate density for leaching and adsorption and is pumped across to one of the

Control of pH in the cyanide leaching process June 2015

2015-05-21· The control of pH in a cyanide leach solution is critical both from a safety and cost viewpoint. The process adds cyanide to solution in the form of sodium cyanide (NaCN). Decreased pH values favour the following reaction: NaCN + H 2 OgHCN + NaOH. The result is the formation of hydrogen cyanide gas, which is lethal in a concentrated state.
