METHOD OF PROCESSING OF COPPER-CONTAINING SLAGS

摘要

nonferrous metallurgy; applicable in production of pure copper in processing of copper-containing slags. SUBSTANCE: method includes slag heating and melting in electric arc furnace. During heating, lime as fluxing agent is introduced into slags to attain basicity of 1.0-1.1. Melting is carried out within temperature interval of 1330-1350 C. EFFECT: higher economic efficiency of claimed process due to reduced consumption of electric power. 3 ex
