    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.

    This study aimed to evaluate the chromite recovery from shaking table tailings of Forumad plant by a dry high-intensity magnetic separation. The average feed grade of chromium trioxide Cr2O3 was 7.62 by XRF. Also different mineral phases were determined by XRD identifying the presence of Chrysotile Augite Albite Chlorite and Chromite.

  • Dissolution and reduction of chromite ore in

    Dissolution and reduction of chromite ore in

    chromite ore was fed into the molten slag and was followed by reduction of iron and chromium oxides. Due to the fact that the chromite ore was fed in granular form as expected a greater contact area was created which influenced the dissolution reduction reaction between the ore and the slag. The slag composition played a significant role .
