Density Of Gold Ore

Gold is a chemical element with the symbol Au from Latin aurum and atomic number 79, Gold has a density of 19.3 gcm3, almost identical to that of tungsten at 19.25 gcm3 as such, tungsten has been used in counterfeiting of gold bars On Earth, gold is found in

The Density of Common Rocks and Minerals

Jan 23, 2020  The densities of rocks and minerals 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).
