Definition: A mineral is a pure inorganic substance that occurs naturally in the earth's crust. All of the Earth's crust, except the rather small proportion of the crust that contains organic material, is made up of minerals. Some minerals consist of a single element such as gold, silver, diamond (carbon), and sulphur.

Introduction to Types of Minerals There are more than 2,800 types of minerals which have been identified on this planet. Of these only 100 are considered ore minerals. An Ore is a naturally occurring rock containing high concentrations of one or more metals that can be profitably mined. Ore minerals are the minerals within ores that contain the metal.
