"Specific gravity" is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rock's "bulk density" arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.

Hematite (iron ore) weighs 5.15 gram per cubic centimeter or 5 150 kilogram per cubic meter, i.e. density of hematite (iron ore) is equal to 5 150 kg/m³. In Imperial or US customary measurement system, the density is equal to 321.504 pound per cubic foot …

Dec 12, 2006· Specific Gravity is how dense a material is compared to the density of water. To be quite honest, none of us will know an specifics about Iron Ore Concentrate's density or specific gravity. We have better things to do then memorize this mostly useless information.

Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l …
