This paper is devoted to a research review on a promising electrochemical method for the production of ferrotitanium. Ferrotitanium is an alloy of iron and titanium with a content of the latter in the range of 20–78%; it is one of the most important ferroalloys used in the production of special steels and alloys. Russia is one of the world’s leaders in production of this product. In Russia, ferrotitanium is produced in two ways: the first is the aluminothermic reduction of titanium concentrate (low percent ferrotitanium). The second is the fusion of iron and titanium waste (high percentage ferrotitanium). However, in recent years there has been considerable interest in the possibility of production of ferrotitanium by electrochemical methods. Electrochemical production of Fe – Ti alloy is potentially more economical process in comparison with existing technologies, since electrolysis is characterized by low labor costs and has a smaller number of manufacturing operations. It is also worth noting that electrochemical processes are safer. In the present work, a brief review of classical technologies for the production of ferrotitanium was carried out and new ways of producing ferrotitanium based on electrochemical processes was analyzed in detail. Most of the considered methods are currently at the stage of laboratory testing, however, the results of the considered studies can be of great importance for the development of the ferroalloy and electrometallurgical industries.
This work was carried out with the financial support of JSC “Romeks” during the fulfillment of the agreement No. 126/18-501 (31.10.2018).
