Chromite Processing Plants: Higher Recovery, More Earnings

Chromite ore, the mineral source of chromium, is predominantly used in the production of ferrochrome-an alloy of chrome and iron. According to MMR, The Global Chromium Mining Market was valued at US$ 17.74 Bn in 2020 and is expected to reach US$ 25.35 Bn by the end of 2027, growing at a CAGR of 5.23% during the forecast period. To Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4).
