Gravity Concentration Coal

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)

Coal, Kentucky Geological Survey, University of Kentucky

The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal, is 4.9 to 5.2. Because pyrite is much denser than .
