Chromite - Wikipedia

Chromite is an iron chromium oxide: FeCr 2 O 4. It is an oxide mineral belonging to the spinel group . Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4 ); [5] substitution of aluminium occurs leading to hercynite (FeAl 2 O 4 ).Chromite smelter process – Grinding Mill China,chromite smelter process. mining process of chromite Rock Crusher.

Process - ASA Metals

At the smelter, charge chrome is produced through a single stage process by smelting a mix of chromite, reductant and fluxes at temperatures in excess of 2000°C. Electrical energy, required for the chemical reactions to occur, is supplied to the submerged arc furnaces, through Söderberg electrodes.An Improved DC-Arc Process for Chromite Smelting,At present, the leading process for ferrochrome is that offered by Outokumpu [2]. This process essentially involves firstly the agglomeration (pelletizing) of the smelting recipe, followed by sintering, cooling, and screening. This sinter is thereafter reheated to 600-700°C and hot charged to a closed submerged electric arc furnace.Ore Processing - icdacr,smelting chromite. These include rotary hearth sintering and pre-reduction of pellets, and fluidised bed pre-heaters for chromite fines. Some intensive development work has been carried out in Japan upon entirely coal/oxygen based smelting processes using no electrical energy, sometimes referred to as smelt-reduction processes.
