Jigging is a kind of gravity concentration method. This method seperates minerals of different specific gravity by their relative movement in response to gravity and ore or more other forces the latter often being the resistance to motion offered by a viscous fluid, such as water or air.
If the ore contains an appreciable amount of sulphide minerals then, if the primary grind is finer than about 300p~m, these should be removed by froth flotation prior to gravity concentration, as they reduce the performance of spirals, tables, etc. If the primary grind is too coarse for effective
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 resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

Gravity separation is used prior to flotation to separate golden particles greater than 0.1 (0.15) mm too. The lower limit size of the use of gravity separation to date is 5 microns. Major losses in golden gravity separation comprise splices of gold with other minerals, platelet-shaped particles of gold, micro and nanoparticles of gold.

Hematite (iron ore) weighs 5.15 gram per cubic centimeter or 5 150 kilogram per cubic meter, i.e. density of hematite (iron ore) is equal to 5 150 kg/m³. In Imperial or US customary measurement system, the density is equal to 321.504 pound per cubic foot [lb/ft³], or …
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, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).
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. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is ...

Density and Specific Gravity defined Density is expressed in terms of mass per unit volume. The density of water, often used for comparisons, can be expressed as 1.0 g/cm3 or 1,000 kg/m3. Mineralogists often use the unit-less measurements of specific gravity, which is the density of a mineral relative to that of an equivalent volume of water. A
Copper ore weighs 2.265 gram per cubic centimeter or 2 265 kilogram per cubic meter, i.e. its density is equal to 2 265 kg/m³. In Imperial or US customary measurement system, the density is equal to 141.4 pound per cubic foot [lb/ft³], or 1.309 ounce per cubic inch [oz/inch³] .
