METHOD for PROCESSING COPPER zinc-containing MATERIALS

摘要

A method for processing of copper zinc-containing materials includes zinc reducing from the slag molten materials with the production of copper and zinc sublimates. At first the melt is poured to the converter with the bottom air blasting and it is blown with the oxidating blasting (with oxygen) to the moment of stopping of sublimation of zinc from the melt, and zinc reduction from slags which was formed is carried out by introduction of ferrosilicon to the bath of converter at the simultaneous blowing out of bath by the rare gas to the moment of stopping of zinc sublimation, after which slag is rolled and melt is additionally treated with oxidating blasting.
