Specific Gravity: The specific gravity of a mineral is the ratio of the density of that mineral compared to the density of water. Specific Gravity can be estimated by ''hefting'' the mineral. To do so, one compares the weight of an unknown mineral sample, to the weight of a known sample of similar size.

Mineral oils specific gravity is important when dealing with electrical equipment. If the oil has a high density the water present would float to the top, which would decrease the oils effectiveness. The API Gravity is a special form of specific gravity that is used to measure of how heavy or light a petroleum liquid is in comparison to water.

Jan 28, 2016· The specific gravity (also called relative density) of a material is a ratio of the density of that material to the density of water at 4∘C, which is the temperature at which water has its maximum density. Density itself is defined as mass per unit volume : ρ = m V. ∴ SG = ρrel = ρs ρwaterat4∘C.

If the specific gravity of a mineral is 5*0 or five times as much as the water, by taking a one liter sample of slurry and weighing it you can determine the percentage of ore that is in the one litre sample. As an example let us say that the weight of the sample was three thousand four hundred grams.

MINERAL PROPERTIES: SPECIFIC GRAVITY. Specific Gravity, also known as SG, is a measurement that determines the density of minerals. Two minerals may be the same size, but their weight may be very different. The specific gravity of a mineral determines how heavy it is by its relative weight to water.
