Gravity Concentration Ore

Mass, Weight, Density or Specific Gravity of Bulk Materials

The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic metre) (see table below)
