Minerals have a wide range of colour, hardness, texture and lustre. They are identified on the basis of their physical and chemical properties. Minerals can be organic in origin or inorganic in oregin.

Organic minerals like coal and petroleum, are also called mineral fuels or fossil fuels.

Inorganic minerals are classified into two groups-metallic and non-metallic.

Metallic minerals are those that contain metals such as iron, copper, aluminium, gold and silver. They are found as ores in igneous and metamorphic rocks. These minerals are hard, have lustre and are generally good conductors of heat and electricity. They are further classified into two types-ferrous and non-ferrous.

Ferrous metals contain iron; for example, manganese and chromite.

Non-ferrous metals do not contain iron; for example, copper and gold.

Non-metallic minerals are those that do not contain metals. They include limestone, sulphur, potash, nitrate, mica and gypsum. They are found in sedimentary rocks. minerals These are soft, do not have lustre and are generally bad conductors of heat and electricity.
