Application of russian ore raw materials to ferroalloys production

Abstract

The main problem of ferroalloy production in Russia is the availability of ore raw materials in domestic factories. Only a few types of alloys are produced from our own raw materials (such as ferrosili-con and vanadium alloys). Most ferroalloys are either imported from abroad or smelted from imported raw materials. The difficult situation in domestic ferroalloy production is associated with raw material import dependence. Despite the presence of its own large mineral resources base, although not quite high-quality in accordance with world standards. Domestic ferroalloy raw materials have a low content of leading elements (manganese, chromium ores), a high content of phosphorus (manganese, niobium ores) and sulfur (manganese ores). This requires a conduction of physical and chemical studies and the creation of a number of new alternative technologies. The work shows that it is possible to create new processes and combinations of different types of ferroalloys from non-traditional domestic ore raw materials based on deep physicochemical and technological studies. They are not inferior in terms of their technical and economic indicators of products obtained from imported materials. To successfully solve the problem of providing the ferroalloy industry with domestic ore raw materials, it is necessary to combine the research of geology, enrichment and metallurgy.
