A Process Mineralogical Evaluation of Chromite at the ...

Chromite is a member of the spinel group and is the only economically important ore mineral of chromium. It is used extensively by the metallurgical industry as feedstock for ferroalloy production [1,2,3,4].Chromite ore is commonly classified into different grades based on the Cr/Fe ratio as well as the Cr 2 O 3 content. These being metallurgical grade, chemical grade and refractory grade [].
