Gold ore CarbonInLeaching (CIL) processing technology
The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the socalled CarbonInLeach process (CIL). The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The goldrich eluate is fed into an electrowinning circuit where gold and other metals are plated out onto cathodes of steel wool. The loaded steel wool
