Chromite - an overview ScienceDirect Topics

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 ...

01/05/2002  It was observed that when the chromite content of the material composition increased from 10 to 28% and 50%, the cold crushing strength (CCS) of the material has decreased, yet its porosity (P%) increased. This improves when the sintering temperature increased from 1450 to 1550 °C and 1750 °C.
