Ferrochromium is a metal used as an alloying material in stainless steel production. It is produced by smelting chromite ores and ferrochromium slag is a byproduct of this process [ 5 ]. It has been reported that more than 1 ton of slag is obtained for producing 1 ton of ferrochromium [ 6 ].

ferrochromium. Stainless steels and superalloys require the addition of chromium via ferrochromium or chromiumcontaining scrap. The value of chromium material consumption was expected to be about 850 million in 2021, as measured by the value of net imports, excluding stainless steel, and was a fourfold increase from 201 million in 2020.

Feb 6, 2021The steel industry uses ferrochromium containing 65 to 70 percent chromium for chromium additions to molten steel. To prepare ferrochromium with this chromium content, chromite having a chromiumtoiron ratio of to 1 must be used. The average chromiumtoiron ratio of Mouat chromite concentrates is to 1.
