Chromite is a mineral that is an iron chromium oxide.It has a chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4).

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

RAPID ANALYSIS OF GHROMITE AND CHROME ORE By JOSEPH I. DINNIN ABSTRACT Rapid methods for the determination of the major and of some minor constitu ents of chromite and chrome ore permit the complete analysis of a dozen or more samples to be performed in about 5 days with a precision comparable to that of the more conventional methods.

Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must .
ore has positive correlation with Cr2O3, the MgO/Al2O3 ratio increases with reduction in Cr2O3 content. Thus, as the Cr2O3 and Al2O3 decreases, the MgO increases. Table 1.

chromite smelter material. Chrome ore (low in silica) was added additionally to increase the resistance to corrosion and thermal shock. The microstructure of the newly developed brick brand is presented in Figure 1. Figure 2 shows the smelter plant (pilot plant at the TCL) in which the fused magnesia-chromite material was produced.
