Extraction of zinc and iron from electrosmelting dust

Abstract

The extraction of zinc and iron from dusty electrosmelting wastes is discussed. The chemical composition of the dust is investigated. Methods of obtaining zinc- and iron-bearing products by reduction are identified. The optimal conditions for the generation and capture of zinc sublimates are determined. A system for processing steel-smelting dust to obtain iron is proposed. Simultaneously, this technology extracts zinc from the dust in the form of zinc-oxide concentrate.
