Effect of Acid Leaching Pre-Treatment on Gold

Low gold dissolutions are due to the high content of copper (around 30%) in PCBs, which has a strong negative effect on the kinetics of the gold-leaching reaction, because copper competes with gold for thiourea with the formation of Cu[CS(NH 2) 2] 2 2+ that prevails over the formation of Au[CS(NH 2) 2] 2 +. This occurrence is less pronounced when gold is recovered from primary raw materials due to the negligible presence of copper in the siliceous or sulphide matrix where gold
