WebThe chromite ore Cr/Fe ratio is of importance as it directly affects the alloy Cr grade whilst the gangue elements affect the melting energy and rate as well as the slag chemistry. The chromite spinel ore morphology can be described stoichiometrically as (Fe, Mg)(Cr,Al,Fe)2O4 and chromite ores often contain gangue elements of SiO2 and MgO. WebIn the industrial process, raw chromite is dried, crushed, mixed with soda ash, and roasted in a rotary furnace in an oxidizing atmosphere. ... whereas high Cr♯ chromite was sought for refining for metallurgical end uses. In recent decades, improvements in processing have made it possible to use either variety for both purposes.
