Gravity Separation - ScienceDirect

The medium used for the separation depends on the specific gravity of the minerals and may be made up of dissolved salts such as calcium chloride in water, where densities around 1350 kg/m 3 may be produced or with zinc chloride where densities up to 1800 kg/m 3 can be obtained. This medium density is low but has been used for the separation of ...
