  • Coppergold ore processing with ion exchange and SART

    The deposit at Gedabek is a coppergold porphyry, comprising both oxide and sulphide ore mineralisation, which is being mined at the rate of about 1 million tons of ore per year Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 12 ppm of gold, together with 1000 ppm or more of copper The PLS isDuring this process, the silver & copper can also be collected CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using flotation and/ or gravity circuits Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density Then it is pumped to leaching plant and dissolvedGold Processing,Extraction,Smelting Plant Design
