The construction of the ferroalloy plant in Zestafoni was determined by two main factors - the neighbourhood with the Chiatura manganese ore and the proximity to highways and ports. The construction of the factory began in 1931, and the first casting day is October 30, 1933, which is officially considered as the first day of the plant operation. By the end of 1937, the plant was producing 11 varieties of ferroalloys, and after that the ferromanganese plant was transformed into a ferroalloy plant. Over the years, the Zestafoni plant has expanded its activities and production capabilities in order to meet the international requirements for the production of high-quality ferroalloys. The enterprise has 12 electric arc furnaces with a high-level air filtering device, a sintering plant and a renovated workshop for manganese briquettes.
