1. What is Chrome Ore? Chromite (massive, equiaxed crystal system) is a magmatic mineral, which often occurs in ultrabasic rocks and coexists with olivine; Also found in placers. It looks like magnetite, which is generally a massive or granular aggregate. 2. What are the chrome beneficiation processes? Alluvial chrome ore washing plant.Commercial chromite ore beneficiation processes. Pure chromium is difficult to produce since it is readily contaminated by many other elements. Huge quantity of raw chromite ore is being mined and beneficiated in various chrome ore beneficiation plants throughout the world to cater the customized needs of various ferro alloy plants.Chrome ore beneficiation challenges & opportunities A
