  • Comparing and Contrasting Mineral Properties

     · Specific gravity is the ratio of the mass of a given volume of a mineral to the mass of an equal volume of water. Simply specific gravity refers to how heavy a mineral feels (density). Magnetism is a property of two common minerals magnetite and pyrrhotite (both minerals contain iron.) This property is unique and therefore easily recognizable.

  • Gypsum Mineral Uses and Properties

    Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite anhydrite sulfur calcite and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

  • The Density of Common Rocks and MineralsThoughtCo

     · 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).
