Stratiform, Podiform, and Beach Sands. Small amounts of chromite are found in many types of rock. However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and …

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 …

mines are already exploiting other chromite layers within the Middle group, and these are the MG2, 3 and 4 [6]. This might be due to depreciation of high-grade chromite seams. Chromite processing involves crushing, milling to less than 1mm and further beneficiation using gravity circuits and spiral concentrators are widely used for this purpose.
