Cyanide Leaching 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.

Control of pH in the cyanide leaching process June 2015

Jun 01, 2015· Plants now also commonly inject oxygen into the leach tanks to help accelerate the leaching process. Since oxygen is a key component in the above reaction, it increases gold recovery for a given residence time in the leach tanks. Usually the leach tanks are large and contain only cyanide solution and pulp.

The process design of gold leaching and carbon-in-pulp

takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in
