Gold ore Carbon-In-Leaching (CIL) processing

2018-11-12  The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL). The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated out onto cathodes of steel wool. The

Estimation of gold inventory in large carbon in leach

2011-5-1  Approximately 50% of the total gold processed by the plant gold is dissolved and recovered onto the carbon. Each tank is charged with a target concentration of 15.0 g/L of carbon. Gold that dissolves from the ore is continuously adsorbed onto the activated carbon. The discharge of the last tank flows to the tailings ponds.

Gold CIL CIP Gold Leaching Process Explained CCD

2013-1-2  Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the gold-loaded carbon. Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.
