Production of ferrosilicomanganese concentrate from tailings slag

  • Published:
Steel in Translation Aims and scope

Abstract

The viscosity and electrical conductivity of MnO-SiO2-CaO-Al2O3 slag melts for the largescale smelting of ferrosilicomanganese in RPZ-63 furnaces at PAO Nikol’skii Zavod Ferrosplavov are investigated. Factors responsible for alloy loss are noted, and extraction of the alloy from tailings slag is considered. Instead of pneumatic separation and hydraulic jigging, a new technology is proposed for sorting of the slag and the extraction of metal concentrate, on the basis of electronic sensors and data-processing software.
