2020-4-10If the ore is amenable to pre-concentration this should be included in the process flowsheet. Pre-concentration via sensor sorting. Most of the chromite concentrate produced is of metallurgical grade with Cr 2O 3 averaging 54 and with a chrome to iron ratio of 2.61. This type of ore is often amenable to pre-concentration at coarse sizes to ...

Process description DMS cyclone plants . The DMS process involves the mixing of a pre-prepared ore stream with a dense medium of selected specific gravity SG in a mixing box and passing this mixture through a dense medium cyclone DM cyclone. It is here that separation of the high and low SG fractions of the ore occurs.
