Minerals vary greatly and their use is in many everyday objects or materials that we use.

Inorganic Oxides such as (TiO2, SiO2, Al203), Calcium carbonate (CaCO3) and Sulphate minerals such as BaSO4) are all common examples of such minerals. Many of these minerals are manufactured as part of a milling process where the particle size is reduced. The resulting particle size is important to the physical properties of the material and how it is used. TiO2 for example is used to make things "whiter". The particle size is directly related to the whiteness of the product by a change in overall opacity of the TiO2 powder itself.
