Chromite and ferrochrome below 1mm is efficiently recovered from gangue minerals by gravity concentration Consulmet has an enviable record in providing flexible solutions combining compact designs with low operating costs
The production of high carbon ferrochrome is a reductive process, and as such changes the oxidation state of the chromium in natural chromite from the plus 3 (Cr3+) oxidation state to zero Unreduced chromium in the slag is in the 3+ state, which is chemically very stable With the older semi-closed processes, some hot dust can be subjected to oxidation and under certain circumstances small

Ferrochrome is an alloy composed of iron and chromium, created in an electric arc furnace when processing chromite ore The importance of ferrochrome lies in the fact that there is no substitute for it Mined chromite is also used to manufacture refractory bricks, furnace linings, and foundry sand It is used in these objects because it has a very high melting point and can withstand very high temperatures

Pre-reduction and flux-aided direct reduction of chromite provide significant advantages in reducing energy consumptions and greenhouse gas emissions resulting from ferrochrome production
Chromite, when presented as an ore, or in massive form, forms as fine granular aggregates The structure of the ore can be seen as platy, with breakages along planes of weakness Chromite can also be presented in a thin section
