DetailsTo determine each minerals specific gravity, a standard to measure each against was needed. The standard that was chosen was the weight of water. 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.
DetailsMineral and rock densities are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
DetailsSpecific Gravity of Gold. The specific gravity of gold is approximately 19.3. This high specific gravity indicates that gold is significantly denser than other metals and substances. Due to its density, gold is considered a heavy, precious metal, prized for its weight, luster, and non-reactive properties.
DetailsHowever, when dealing with these situations, gravity concentrators can still be effective at mitigating risk at a low cost. Almost all gold ore grades fluctuate and are susceptible to the nugget effect. If gold particles cluster in specific locations and leave gangue everywhere else, there can be a wide variation in sample test results.

In my method the same example (above) lead to results in these measurements:
DetailsThe Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature.
