Abstract
Research and development of technological aspects allowing the involvement of domestic manganese ores into ferroalloy production to cover the needs of national steelmaking are of interest to the Russian metallurgical industry. As domestic manganese ores have low manganese and high phosphorus content, they have to be subjected to processing and dephosphorization. One of the most promising manganese ore deposits among proven ones is the Usinskoe mining deposit with the biggest reserves of manganese in Russia. Manganese ores of Usinskoe mining deposit have comparatively low manganese content (18–22%) and high concentration of phosphorus (0.2–0.3% and more). On the basis of previous research and development results, a technological scheme was proposed for carbonaeous and oxide ores of Usinskoe mining deposit. Chemical composition of manganese concentrates allows us to propose technological schemes of manganese ferroalloy smelting. Chemical compositions of final ferroalloys and technological schemes, including specific consumption of materials, are given in this paper.
