  • bulk density calculation in mining

    The bulk density of a powder is the ratio of the mass of a powder sample and its volume.The bulk density is expressed in grams per mL(g/mL) or g/cm3. It is divided into loose bulk density and tapped bulk density. The bulk density of a powder is often very difficult to measure with good reproducibility.

  • Specific Gravity and Bulk Density Mining SGS

    “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.
