    Foundry Grade Chromite sand is a complex compound of various elements. The main elements Chromium as Cr2O3, Aluminium as Al2O3, Silica as SiO2, Magnesium oxide as MgO. It is a lustrous, brittle, hard metal. Its colour is silvergrey and can be highly polished. It does not tarnish in air, when heated it burns and forms the green chromic oxide.

    Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.

  • Flotation of chromite and serpentine

     · Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silies. A good knowledge of the flotation behaviour of chromite and the establishment of conditions for its selective separation from the gangue minerals might help the future exploitation of chromite deposits.

  • New heavy mineral spiral for recovery of ultrafine chromite

    New heavy mineral spiral for recovery of ultrafine chromite. Spiral concentrators are gravity separation units which are cost and energy efficient. They are widely used to treat various minerals such as coal, iron ore and chromite ore. Separation is based on the difference in the specific gravity of the compounds in the mineral ore.

     · Since most chromite ores are easily beneficiated with gravity concentration methods, flotation of chromite has not been widely applied or got commercial acceptance (Atalay and Ozbayoglu, 1992). This is the most essential issue of every gravity separation circuit in mineral processing plants, which causes loss of large fraction of the valuable minerals into tailings.
