A general chromite ore mining process consists of two sections: 1. Comminution Chrome lump ore must be crushed and ground into powder due to medium and fine dissemination grain sizes. While chromite sand ore does not need the two steps. For example, most of the chromite mines in the Philippines and Vietnam are chromite sand.

Chromite ore was first explored in northeast region in 1940 in Iran, but chromite mines started their operation in 1950 in southeast region in Esfandagheh and Faryab mines. Since almost all countries in the region had a same tectonic story, they are in same potential in chromite reserves like Iran, Oman, and Pakistan; nevertheless Turkey and Kazakhstan with a far distance are on top of this

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, whereas lower-grades are subjected to different dressing procedures).
