How to Find and Determine the Specific Gravity of a Rock
To determine the specific gravity of a mineral, you simply take a sample of ore of known size and put it into a volume of water. Weigh the water that was displaced by the mineral.

Simply put, pre-concentration drastically reduces the ore mass that reports to intensive downstream processing. By using gravity to recover mineral-bearing particles into a much smaller volume, significant savings in energy and operational expenses are achieved.
Density, Specific Weight and Specific Gravity - An introduction to density, specific gravity and specific weight - formulas with examples Minerals - Density - Densities of minerals Mohs Scale of Mineral Hardness - Qualitative ordinal scale that characterizes the scratch resistance of various minerals
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)

Concentration Definition: The process of removal of the gangue from Ore is known as Concentration or Dressing or Benefaction. There are numerous methods of concentration and the methods are chosen based on the properties of the ore.
The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products.
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 …

It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated C C {displaystyle CC} in the following equation (where S G {displaystyle SG} represents specific gravity ):
During the exploration phase gravity concentration can help define a more accurate grade when there is a nugget effect with a given ore. Expertise The Met-Solve team is lead by Ish Grewal, one of the world's leading gravity concentration experts, and continues to remain on the cutting edge of gravity concentration technology.
Gravity concentration methods separate minerals of different specific gravity by their relative move- ment in response to gravity and one or more other forces, the latter often being the resistance to motion offered by a viscous fluid, such as water or air. It is essential for effective separation that a marked density difference exists between the mineral and the gangue. Some idea of the type ...
