OKTOP® CIL Reactor

CIL and CIP processes utilize activated carbon to adsorb solubilized gold for recovery. Due to carbon attrition and non-ideal carbon management, however, some of the gold is lost in carbon fines and to the solution. The cyanide leaching of Au and dissolved Au recovery to activated carbon are the key process steps in gold mine operations to produce gold doré bars.
