This article discusses various technologies for producing chromium ferroalloys from non-conditional raw materials. Every year, about 13-14 million tons of chromite ores are mined in the world, the content of the 0-10 mm fraction in which is 75-80%, of which about 30% is in powder or pulverized form. In Kazakhstan, the main preference is to use rich ore, not using poor (substandard) ore. The dust captured by the aspiration units is a fine particle of a fraction of 0.01-1 mm with a metal chromium content of 65-69%. Due to the fineness of the material, it is almost substandard. The volume of generated aspiration and other dust of interest from the point of view of processing into conditioned materials is more than 25,000 tons per year. The crushing of high-carbon ferrochrome produces 1000 tons of aspiration dust per year. Hence, there is a need to study technologies for producing chromium ferroalloys from substandard raw materials. The study of this technology is important not only from the economic, but also from the ecological side. After all, low-quality raw materials are used in small quantities, and the bulk of it is stored in landfills. The data obtained by us are of theoretical value and will be used for laboratory research.
