CIL gold processing plant

CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size (typically 90% passing 200mesh ) to ensure that all non-refractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multi-stage crushing, then ball milling circuits, typical of ball mill and hyrocyclon...

Electrowinning

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching Electrorefining uses a similar process to remove impurities from a metal Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non ....
