south africa holds approximately three-quarters of the world's viable chromite reserves (loock et al., 2014). the most important historic sources of chromite from podiform deposits are in kazakhstan, turkey, and albania (papp and lipin, 2001a,b; papp, 2010).

most of the world's known chromite occurs in two stratiform deposits: the bushveld complex in south africa and the great dyke in zimbabwe. other important stratiform deposits include: the stillwater complex in montana, the kemi complex of finland, the orissa complex of india, the goias in brazil, the mashaba complex of zimbabwe and small deposits in madagascar.
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

the world's largest stratiform chromite deposits are found in south africa, in what is known as the bushveld complex. this is a layered igneous intrusion containing more than 11 billion metric tons of chromite resources.
south africa is the world’s dominant producer and exporter of chromite, and its large resources of chromite are located in the western and predominantly in the eastern limbs of the bushveld igneous complex (bic). the country hosts 70% of the world’s
south africa is the largest producer of chromite ores, where over 70% of world chromite ore reserves are believed to be located. today south africa supplies approximately 50% of world's supplies of chromite ores. other countries playing a significant role in the supply of chromite ores are kazakhstan, india, turkey, zimbabwe, russia, brazil,
chromite mines have produced 57.4 percent of the world’s total chromite production (stowe, 1987b). in 2010, about 25 percent of the world’s chromite production came from podi-form chromite deposits, and this percentage has held for the past 50 years (papp, 2011; leblanc, 1987). podiform chro-
