  • Separation and Concentration Mineral Processing ...

    Dense Media Separation (DMS) is an enhancement of gravity situation in which ore is fed into a solution with a density between those of the mineral and gangue, respectively, with one product rising toward the surface for collection and the other being discharged at the bottom of the vessel. Coal and chromite are often collected by this means.

  • Magnetic susceptibilities of minerals - USGS

    Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.
