Pyrometallurgical Processing of Copper-Smelting Slags

t is considered an actuality and problems of the Copper-smelting slags processing. It is formulated the demands, which the slag processing technology must to conform. It is given the ground for preferableness of the pyrometallurgical method, which it is caused the next factors: a) variety of slag composition, forming on the Copper founding plants and b) necessity of its selective proceeding with using the individual technology regimes. It is offered the two stage technology for Copper slag pyrometallurgical processing, which allows to extract from slag the metallic part during the separating smelting, and during the reducing smelting to extract the metallic components from nonmetallic part, where its presents at the chemical combined condition. It is presented the experimental dates about output of metal during the every smelting stage and the kinetic of reducing extraction.
