Silicomanganese production at transalloys in the twenty-tens

Abstract

Transalloys is currently the largest producer of silicomanganese in Africa, with its smelter complex based outside the town of eMalahleni, in the Mpumalanga Province of South Africa. It operates five open submerged arc furnaces and produces an alloy containing > 16% Si, < 2% C, and > 65% Mn. Manganese ore is the main source of manganese units, supplemented by dust and alloy fines recycled into the furnace as briquettes. Transalloys has mature technology and systems in place, which are described in more detail in this paper.
