Effect of Acid Leaching Pre-Treatment on Gold Extraction ...
2021-1-13 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 ...
