Chromium Concentrate
Chrome ore is the common name for the mineral chromite, which is described in the technical literature as an iron chromium oxide. Chrome ore is mined and is used predominantly in the metallurgical industry. It’s the rare earth materials produced by floating process using spiral processor and crusher. Silica is separated by help of water through which the friable ore float through and concentrate come as residue having maximum percentage of chrome ore. The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant super alloys, nichrome, and stainless steel. Chromium is used as a pigment for glass, glazes, and paint, and as an oxidizing agent for tanning leather. It is also sometimes used as a gemstone.
