  • concentration of ores gravity separation Serious Laser

    Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

  • EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE

    2012-5-15 · Fatma et al. (1999) studied the beneficiation of an iron ore sample containing 44% Fe, 1.59% SiO 2 and 20% BaO. By magnetic separation, two products of iron ore and barite concentrates were obtained by using a high intensity magnetic separator. The fine fraction (-0.125 mm) is about 20% by weight assaying 54.6% Fe, and 3.91%

    Even if the actual V lg was 57% instead of 60%, the low gravity concentration would be 34% volume. In most cases the decision to continue running the mud cleaner would not be affected by this inaccuracy. Even if the barite in the discard exceeded the low gravity concentration, the benefits of removing those larger solids will be evident. Accurate results, of course, can be
