In a CIP plant, leaching is complete before the first adsorption tank, and gold is then recovered from the leached pulp in a series of 410 dedicated carbon adsorption tanks. In a CIL plant, the carbon is added directly into the leach tanks, with the claimed advantage of lowering capital costs by eliminating the CIP adsorption tanks.
effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg robbing at the ore surface. A variable order empirical
plant, leaching is complete before the ﬁrst adsorption tank, and gold is then recovered from the leached pulp in a series of 410 dedicated carbon adsorption tanks.
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon in leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks so that leaching and adsorption take place in the same tanks.
CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size 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 hyrocyclones.
