Who is the biggest ferrochrome producer?

The largest producing countries of ferrochrome are South Africa, Kazakhstan, India and China.

How is ferrochrome produced?

Ferrochrome is manufactured by conducting carbothermic reduction of iron magnesium chromium oxide under high temperatures. Iron-chromium alloy is produced by the reduction of Chromium Ore by the application of coal and coke. This reduction process requires heat which comes from the electric arc of the furnace.

What is ferrochrome slag?

Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 °C and its main components are SiO2, Al2O3 and MgO. Additionally it consists of chrome, ferrous/ferric oxides and CaO.
