Jan 03, 2018· Recall that Specific Gravity is the ratio of the density of a substance to the density of water. The density of water varies less than 1.5 mg/cm3 over the narrow range of normal temperatures. Between 20o C and 25o C the density of water is essentially 1 g/cm3. The volume expansion of the solid mineral is insignificant.
The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.
In this example of the specific gravity test, we use gold mixed with quartz. Nugget weighed in air weighs 96 grams. Nugget suspended in water weighs 74.5 grams 96 - 74.5 = 23.5 96 divided by 23.5 = 4.17 (the specific gravity of the specimen) 4.17 - 2.63 (the average specific gravity of quartz) = 1.54
The value of 19.3 used below for the specific gravity of gold is too high for placer gold. This was only used for comparison to other web sites. Assuming that the specific gravity of gold is 19.3 and the specific gravity of quartz is 2.65, we have: A = 19.3 / (19.3 - 2.65) = 1.16 B = 2.65 A * B = 3.07 which for the first method results in

Specific gravity is the ratio of the mass (weight) of a rock to the mass of the same volume of water. Water has a density of 1.0 g/cm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit. Specific gravity is easier to measure than density.
