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

Its specific gravity is almost identical to quartz and feldspar, thus ruling out the possibility of gravity

A Open End, End Peripheral Discharge, CPD Rod Mills and Grate Discharge Ball Mills are particularly efficient for dry grinding. Such materials as limestone, cement clinker, gravel, phosphates, clays, gypsum, oil shale, terra cotta mixtures, coal and coke are economically reduced in size through their use. Many such applications indicate the use of open circuit coarse grinding and in such
