Occurrence and Characteristics of Chromite Deposits ...

The chromite deposits of the eastern Bushveld Complex occur in the Critical Zone, a layered pile consisting mainly of pyroxenite, norite, and anorthosite, with minor gabbro, dunite, and harzburgite. With probable reserves in excess of one billion tons, the deposits are among the major mineral resources of the world. The Critical Zone is more than 75 miles long and is divisible into several sectors. The

Upgrade of these materials will result into economically marketable chromite sand. Low grade chromite can also be processed and upgraded for foreign markets like China. Million Link Chrome Limited constructed a modern processing plant in Barangay Pinagrealan, Candelaria for the purpose of upgrading low grade chromite and tailings for overseas market. The processing plant can process up to thirty thousand tonnes of marketable chromite

Chromite mining - Oregon Encyclopedia

Most deposits of chromite in Oregon have been found near Grants Pass on the Siskiyou National Forest and near John Day on the Malheur National Forest. Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict.

Chromite deposits in the Oman ophiolite are invariably associated with dunite bodies occurring dominantly within the upper part of the basal harzburgite unit of the ophiolite, the 'Mantle Sequence'. The host harzburgite and the dunite/chromitite suite show textural and geochemical evidence of origin by different genetic processes. Harzburgite has tectonite textures from polyphase deformation ...

In addition to hosting the largest chromite deposits, it is also the largest known layered intrusion in the world. The Bushveld Complex also contains the largest resources of platinum-group element mineralization. Cousins proposed that the 13 chromitite layers found in the Critical Zone of the Bushveld Complex be grouped into the Lower Group (LG), Middle Group (MG) and Upper Group (UG) based ...
