Selective Leaching of Gold from Copper Anode Slime Using Concentrated Hydrochloric Acid and Hydrogen Peroxide

Selective Leaching of Gold from Copper Anode Slime Using Concentrated Hydrochloric Acid and Hydrogen Peroxide

Leaching of copper anode slime using hydrochloric acid (HCl) and hydrogen peroxide (H2O2) is performed to recover Au. It is imperative to reduce the amount of the costly oxidizing agent, H2O2, used in this leaching. In conventional conditions, the Se contained in the slime is oxidized and dissolved...
