  • Chrome Ore Foundry Sand — Clover Alloys

    The overwhelming majority of the chrome ore produced globally is smelted into ferrochrome, for use as an alloy in stainless steel. In order to be suitable for use as foundry sand, chrome ore has to meet several strict criteria. Its chrome oxide (Cr2O3) content must be above 46% and its silica (SiO2) content must be below 1%, otherwise its

  • CHROMITE (Iron Chromium Oxide)

    Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies.

  • Chromite: The only mineral ore of chromium metal

    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.
