Anode slime is the byproduct of copper or lead electro-refining process and found in electrolytic cell bottom or on the anode scrap surface. The copper anode slime and lead anode slime usually contain precious metals like gold and silver.

Depending on the treatment capacity, process of anode slime recovery is achieved by two different methods, i.e. pyro-metallurgy and hydrometallurgy.

Focusing on high demand of precious metal recovery and large treatment amount, Metalcess offers solution of TBRC smelting + lead distillation & gold metal extraction.

Pressure leaching can be used to pretreat anode slime for environment consideration.
