It depends on the amount of impurities it may contain but the Density or specific gravity varies between 3 175-3 184 to 3 56 if high in rare-earth elements
Gravity Concentration has been used for the beneficiation of minerals for centuries with little change in the methods used from 500 B C to 1550 A D and in fact some of these methods such as the sluice and hand pan are used to this day gold platinum diamonds barite fluorspar tin and tungsten ores Mineral jigs have also been used

The Barite Beneficiation Process is one of flotation Barite-Fluorspar-Zinc Ore Grinding Gravity concentration is sometimes advantageous in conjunction with flotation as by this means products may be obtained that will meet the requirements of more than one market Some of the anionic reagents commonly used to float the barite are
A method is disclosed for beneficiating a fluorspar concentrate containing apatite as a gangue mineral which includes further concentrating the fluorspar by a froth flotation process wherein the apatite is collected and floated with a cationic reagent in an acid flotation circuit and the fluorspar is depressed with fluoride ions
Gravity Concentration Gravity concentration processes rely on the principal that gold contained within an ore body is higher in specific gravity than the host rocks that contain the gold 4 Elemental gold has a specific gravity of 19 3 and typical ore has a specific gravity of about 2 6 All gravity concentration devices create movement
Anhydrite or anhydrous calcium sulfate is a mineral with the chemical formula CaSO 4 It is in the orthorhombic crystal system with three directions of perfect cleavage parallel to the three planes of symmetry It is not isomorphous with the orthorhombic barium and strontium sulfates as might be expected from the chemical formulas Distinctly developed crystals are somewhat rare the mineral

A combination of classification initially screens to remove the coarser impurities then hydrocyclones to remove the finer impurities with some barite loss gravity calcite fluorspar silica from barite and sulphides from barite and flotation oleic acid alkyl sulphonates sulphates with sodium silicate as the dispersant and neutral to alkaline pH - barite is depressed at acidic pHs
The results depicted by density and chemical assay analysis eliminates the use of gravity separation and magnetic separation techniques since the fluorspar tailings will require uneconomic settling times during gravity separation and is not coarse enough for effective magnetic separation 3 2
Gravity concentration process is the oldest beneficiation method known to mankind This is a physical process and exploits the differences in densities of minerals to bring about a separation Although with the advent of froth flotation the relative importance of gravity concentrat-ion has declined in twentieth century but still on an average higher tonnage of material is treated by gravity
