An Overview of Process Options and behavioral Aspects of the Copper values recovered from the Copper Bleed Stream of a Copper Smelter developed at the National Metall-urgical Laboratory

Abstract

In the present research, an effort has been made to prepare copper salt=powder from the copper bleed stream generated during the electrowinning of pure copper from the copper anode in a copper smelter. Various approaches have been opted for the complete recovery of copper values such as: evaporation–crystallization, electrolytic process, and direct hydrogen reduction.
