    Jigging or Dense Medium Separation - Which is the Best?

    A considerable debate has arisen regarding the best route for the beneficiation of iron ore. Supporters of jigging technology claim that although the technology is old, due to recent advances in jig control and a better understanding of the separation processes within jigs, it offers significant advantages over dense medium separation, especially in terms of reduced capital

    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. Bond Equipment DMS plants
