Purpose: Ferroalloys are mainly used in steelmaking processes in order to obtain an appropriate chemical composition of metal. Main producers include China, South Africa, India, Kazakhstan and Russia. These countries in total constitute 83% of the global production. In 2009 nearly 30 million tons of ferroalloys were produced, mainly ferrochromium, ferromanganese and ferrosilicon. Design/methodology/approach: It is presented a review of current methods in the production of chromium and manganese alloys, chemical reaction which take place, advantages and disadvantages of technologies. Findings: Paper shows a situation in the production of ferroalloys based on FeNm and FeCr. Research limitations/implications: This paper presents currently used methods in the production of ferromanganese and ferrochromium. Originality/value: The article presents the share of production of ferroalloys in the world, major manufacturers and used methods.
