Minerals are naturally occurring elements or compounds. Most are inorganic solids (apart from liquid mercury and a few organic minerals) and defined by their chemical composition and crystal structure. By weight, 99.5 per cent of minerals are formed from only 12 of the natural elements. Clearly, some elements are far more common than others.

Hydroxides are compounds of metallic elements with water or the hydroxyl anion (OH)-. Examples of hydroxides are manganite (MnO (OH)), goethite (FeO (OH)), and gibbsite (Al (OH)3; one of the main components of bauxite). Minerals of the hydroxide class are typically softer than oxides and are of low to medium density.
