  • MINERAL GALLERY

    Specific gravity is a unitless measure, because it is derived from the density of the mineral divided by the density of water and thus all units cancel. However, since water''s density equals 1 gram per cubic centimeter (at specific conditions), then a mineral''s specific gravity would also correspond to a mineral''s density as expressed in grams ...

  • Gravity Concentration

    The minerals in the sands are subject to gravity concentration, and some concentrates are significantly radioactive, up to 4000 Bq/kg. Most of this NORM ends up in the waste streams from mineral processing (often including monazite) and so, apart from zircon, the final product is itself devoid of NORM.
