Copper concentrate process

Mar 25, 2021

a hydrometallurgical process to economically treat copper sulfide concentrates. After a review of numerous methods which have been proposed, the chromic acid method is described. The process chemistry indicates that the sulfide mineral should react rapidly with Cr(VI). Oxidation of sulfur to sulfate ion and dissolution of pyrite are signif
