Theoretical Foundations and Technological Capabilities of Hydrocarbonyl Process of Recovering Copper from Technogenic Wastes

Abstract

Secondary processing of waste from metallurgical and other industries becomes an urgent issue in the face of increasing anthropogenic pressure and a shortage of sources of materials. The paper shows the results of chemical and technological studies of processes, executing in the Cu(II)-Cu(I)-Cl-CO-H 2 О system. The processing technology of copper-bearing intermediate products multicomponent leaching solutions, permitting high purity copper production at the least economic cost, is proposed.

Advances in Raw Material Industries for Sustainable Development Goals

“…Despite the prevalence of pyrometallurgical processes, the global copper production by implementing hydrometallurgical approach increases (Fedoseev et al, 2018;Boduen et al, 2019). Amongst current technologies, an alkaline sulphide hydrometallurgical process has been demonstrated successful results in selective dissolution of arsenic and antimony from a copper concentrate containing enargite and tennantite (Prada et al, 2014;Tongamp et al, 2009;Baláž et al, 2006).…”
