Hydrometallurgical treatment of copper smelter dusts. Desarsenification of leaching solutions
Keywords:Hydrometallurgical treatment, Copper, Arsenic, Smelter dusts, Impurities, Purification
Copper smelter dusts contain along with this metal, which is amenable for its recovery, a number of other metals (especially arsenic) which are considered as toxics. Different alternatives have been proposed for the treatment of such metallurgical residues and among them Hydrometallurgy shows good perspectives for its application in this field. In the present work different hydrometallurgical processes proposed for the treatment of copper smelter dusts are described and evaluated together with different alternatives given for the desarsenification of the leaching solutions.
