Chromite an overview | ScienceDirect Topics
Chromite ore has a spinel structure with a general formula of (Fe,Mg)O.(Cr,Al,Fe) 2 O content of Cr 2 O 3 for metallurgicalgrade chromite ore is in the range 42–55% and the chromiumtoiron ratio is higher than These quantities determine the chromium content in the smelted chromium ferroalloys. Magnesium oxide and alumina are refractory at the smelting temperature and fluxed with ...
