As one of leaders of chromite is an iron chromium oxide mineral and the only ore of chromium metal industry, SBM always seeks innovation & excellence.
However, this diamond deposit has a reducing environment, which helps produce small quantities of elemental chromium. Commonly it is found in numerous ores, usually in the mineral chromite. Chromite is the complex of (FeCr_2O_3), or iron chromium oxide. Chromium is also found in other minerals, including magnesiochromite ((MgCr_2O_4)).

Chromium. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
