  • Specific Gravity and Bulk Density | 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.

  • Properties of Gold & Alloys

     · A second series of experiments on a telluride ore from Western Australia, containing over 1,000 ozs. of gold per ton, gave similar results. The losses incurred in roasting gold tellurides are probably due to fine dust being carried away mechanically, or to the absorption by the furnace bottoms of the very fusible mixtures which are formed.

    The solution full of gold, known as "pregnant" solution is decanted or siphoned off. Then, to recover the gold in a solid state, zinc dust is added. This precipitates the gold from the solution. By means of amalgamation and cyanidation over 90 percent of the gold contained in the original ore is extracted.
