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

2009-8-27  After leaching, the pulp is passed over a feed screen to ensure removal of tramp material such as wood-chips, plastics and grit larger than about 0.6 mm. This is done to minimize screen blocking in the adsorption section. After feed pre-screening the pulp flows through a cascade of well-mixed adsorption tanks, typically 6 to 8 in number.

Six Factors That Influence Gold Leaching in Gold

2019-4-12  Gold cyanide leaching is a relatively slow process, the leaching time is over 24 hours generally,and the gold leaching rate is improved with the extension of leaching time, but the gold leaching speed is reduced corresponding, and finally the gold leaching rate tends to a limit value. At that time, even the leaching time is extended,the gold leaching rate of is not improved obviously.
