What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr2O4). It is dark gray to black in color with a metallic to submetallic luster and 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 …

The role of water-rich solutions in the formation of chromitites has been the matter of controversy. We found small chromite concentrations (chromitites) in diopsidites, precipitated from high-temperature hydrothermal fluids, in the mantle to the crust of the Oman ophiolite. Here, we present petrologic characteristics of the hydrothermal …

Chromite sand has a small linear shrinkage, which is a factor that may cause sand inclusion in castings, so it can be used to mix green sand molds for large castings. The chromium ore is sintered with fine particles to eliminate metal infiltration, accompanied by cooling and high residual thermal strength. 4. Chromite sand is universal, it can ...
