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.

ore gravity concentration plant for sustainable development Y. Rama Murthy1 and S.K. Tripathy1,2 Synopsis India has limited resources of chromite. To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing.

The Zambales ophiolite is the major source of chromite ore in the Philippines. The chromitites are concordant cumulates and are associated with distinct chromitite-bearing sequences within the mantle peridotites. Refractory and metallurgical chromite deposits are spatially separated and related to different lithologic associations, which crystallized from different parental magmas ...

To use a chromite ore directly as an input for smelting FeCr, the ore generally needs to contain more than 49 wt% Cr2O3 Chromite ores with Cr2O3 content lower than 49 wt% need to be further upconcentrated by mineral processing techniques (eg, magnetic separation, gravity separation, flotation, etc) [13]
