Abstract

The least utilized recyclable wastes from mining and processing enterprises are dispersed wastes, which are in the form of dust captured by systems of gas purification. This dust is a technogenic raw material for the production of zinc and other metals. Various ways of utilizing the steelmaking dust are presented. For utilization of the steel-making dust, a hydrometallurgical method with the use of autoclave technologies is proposed. The results of experiments in sulfate autoclave leaching are described.

Keywords:
dispersed zinc-iron-containing waste the extraction of zinc pyrometallurgical and hydrometallurgical methods of waste processing autoclave leaching
