METHOD FOR PROCESSING LOW AUTOGENEOUS RAW MATERIALS IN WEIGHED Smelting Furnaces

摘要

1. A method of processing low-autogenous raw materials in a suspension smelting furnace, comprising supplying a metal-containing charge and flux in the form of a charge gas torch into the reaction zone of the said furnace with a stream of oxygen or oxygen enriched oxygen, melting the charge with the formation of matte and slag melts, separating the latter by settling, separate liquid output melting products and gases, characterized in that a carbon-containing reducing agent with a grain size of 3-15 mm is introduced into the mixture in volumetric ratios with a flux from 1:30 to 1: 2.2. The method according to claim 1, characterized in that, as a carbon-containing reducing agent, coal or products of its processing (coke, semi-coke, coal mines, etc.) are introduced into the charge composition.
