How to Find and Determine the Specific Gravity of a Rock
To 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.

Specific gravity & bulk density
The specific gravity or bulk density of rock is essential information for ore reserve calculations. Often, bulk density of rocks is determined using the water displacement method soon after drilling. This can be more challenging in parts of a resource where rocks are highly weathered and can disintegrate upon submersion in water.
