mining chromite technique

Chromium processing | BritannicaChromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr2O3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40.mining chromite technique,Case Study: Chromite mining and processing - oahppchromite mining: • broad potential health effects related to chromite mining and processing beyond concerns arising from chromium exposure. • sensitization to chromium. • mitigation strategies to prevent exposure. • environmental fate and transport of chromium.
