Preparation Of Chromite Ore In Mining

Chromium processing Britannica. 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 chromium iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used.

Chromite Beneficiation Process

The Problem with Chromite Processing Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious that
