The default values below are for gold, using an average specific gravity of 18.6, and quartz, using a specific gravity of 2.65. These values assume a specimen of gold in a matrix such as quartz. However for a gold nugget, containing another mineral such as silver, use the specific gravity of pure gold, 19.3, and pure silver, 10.5.
Gravity ConcentrationGekko. Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses.
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units.
