Mihail I. Gasik, in Handbook of Ferroalloys, 2013 8.2.3 Chromium Ores and Chromites Processing. Chromite ores, as might many others, be mined by open-pit and underground methods. The share of underground mining varies between countries and deposits. The extracted ore is subjected to crushing and sorting (normally rich ore containing more than 45% Cr 2 O 3 is supplied to the processing plant ...

For the case study metallurgical grade chromite ore considered, the optimum pre-oxidation temperature was found to be 1000 °C. Utilising such pre-oxidised ore could theoretically lead to an improvement of approximately 8.5% in the specific electricity consumption and a 14% decrease in the lumpy carbonaceous material required during submerged arc furnace smelting of pelletised chromite …

By exposing chromite ore to aboveground conditions that promote weathering and oxidation, Cr-III may be converted to mobile Cr-VI. Dry milling (grinding) of chromite ore is now known to convert Cr-III to Cr-VI and efforts are required to avoid producing and spreading hexavalent chromium during mining activity.

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.

Previously it was proven that dry milling of chromite ore (and other Cr containing materials) leads to Cr(VI) formation (Beukes and Guest, 2001, Glastonbury et al., 2010). Although not common, some chromite ores, e.g. chromite of the Sukinda belt of Orissa (India) might contain Cr(VI) that occurs naturally (Section 2 ) ( Godgul and Sahu, 1995 ...
