What are minerals?
A mineral is a natural substance with distinctive chemical and physical properties, composition, and atomic structure. The definition of an economic mineral is broader, and includes minerals, metals, rocks and hydrocarbons (solid and liquid) that are extracted from the earth by mining, quarrying and pumping. Economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply.
Economic minerals include: energy minerals, metals, construction minerals and industrial minerals.
Energy minerals are used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics. Energy minerals include coal, oil, natural gas and uranium.
Metals have a wide variety of uses. For example, iron (as steel) is used in cars or for frames of buildings, copper is used in electrical wiring, and aluminium is used in aircraft and to make drink cans. Precious metals are used in jewellery and mobile phones.
Construction minerals include sand and gravel, brick clay and crushed rock aggregates. They are used in the manufacture of concrete, bricks and pipes and in building houses and roads.
