The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a breakthrough impact on the economics of gold ore processing, as the world gold industry entered a period of unparalleled expansion following the deregulation of the gold .
is by adsorption onto activated carbon. For heap leach operation, gold cyanide is extracted from pregnant leach liquors onto carbon in a series of columns, by upflowing leach solution through columns that are packed with carbon. The process is known as carbon-in-columns (CIC). For mill, agitated-tank leaching operations,
The main differences lie in the preparation of the slurry and method for removing the gold from the leachate. In a CIL process, the carbon is mixed with the leachate solution, not with pulp. This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process. Carbon .

Alluvial Gold Ore Processing Plant Machinery. Gold cil process carbon in leach is an efficient method of extracting and recovering gold from its orey cyaniding and carbon leaching crushed gold ore slurry simultaneously, cil process lowers the gold mining operation cost and increases gold recovery rate to a degree of 99old cil processing line.
Activated Carbon Equipment and Process Design. As a leader in custom thermal processing equipment, FEECO provides both direct- and indirect-fired rotary kilns for producing activated carbon from a variety of sources, including coal, coconut husks, crop residue, and wood chips. We also provide kilns for carbon reactivation.
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 hyrocyclones.
The carbon moves to a stripping vessel where a hot caustic solution separates the gold from the carbon. Another set of screens filters out the carbon grains, which can be recycled for future processing. Finally, the gold-bearing solution is ready for electrowinning, which recovers the gold .
