Mining and concentrating Chromite 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 Cr 2 O 3 and having a chromiumiron ratio greater than 21 is preferred but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also usedMore Details

Beach sand rich in chromite and other heavy minerals is sometimes mined processed to remove heavy minerals and returned to the environment Two facts allow these chromite sands to occasionally contain economic deposits of chromite First chromite isMore Details
There are four main mining methods underground open surface pit placer and insitu mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable depositsMore Details
The first way in which proposed mining projects differ is the proposed method of moving or excavating the overburden What follows are brief descriptions of the most common methods 1131 Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground necessitating the removal of layer uponMore Details
