EVALUATION OF ELECTROCHEMICAL TECHNIQUES FOR THE QUANTIFICATION OF GLUE IN COPPER ELECTROWINNING ELECTROLYTES

Abstract

Copper electrorefining is the purification process where anode slabs with around 98% copper content are introduced and dissolved in electrolyte solution to produce cathodes that contains 99.99% pure copper through re-deposition. Major amount of copper is produced through this process. In 2015, total 23 million tons of copper have been refined, in which 18.9 million tons of copper was produced by electrorefining process, and the amount of electrowon copper was 4 million tons [1].
