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

A Process Mineralogical Evaluation of Chromite at the

Chromite ore is commonly classified into different grades based on the Cr/Fe ratio as well as the Cr 2 O 3 content. These being metallurgical grade, chemical grade and refractory grade . Historically most of the chromite mined in South Africa was sourced from the Bushveld Complex. The Bushveld Complex hosts the largest chromite deposits worldwide . In addition to hosting the largest chromite deposits, it is also

A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate ore with disseminated chromite), PCMZ_HG (high-grade Ni-Cu sulphide silicate ore
