Gravity separation of iron ore beneficiation

Jan 01, 2015 Another notable difference is that while coal DMS can use a cheaper medium made up of ground magnetite particles, the higher separation densities required in iron ore beneficiation (in the order of 3–4 kg/l) necessitate the use of relatively expensive FeSi. 10.2.2.

    The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores

    There are many mineral processing methods, and there are two commonly used methods (1). Roasting magnetic separation Roasting magnetic separation is one of the effective methods to separate fine to fine ( 0.02mm) weakly magnetic iron ore. When the minerals in ore are complex and it is difficult to get good indexes by other methods, magnetization roasting magnetic separation should be used
