Mineral Processing Dense Media Separation Bond

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.
