Explanation:
Minerals are naturally occurring substances that have a definite chemical composition.
Minerals are formed in different types of geological environments, under varying conditions.
Minerals can be identified on the basis of their physical properties such as colour, density, hardness and chemical property such as solubility.
Minerals are distributed in rocks and sea bed also.
Tropical regions are very rich in terms of mineral resources.
Types of Minerals:
On the basis of composition, minerals are classified into metallic and non-metallic types.
Metallic, minerals contain metals in raw form.
Metals are hard substances that conduct heat and electricity and have lustre or shine. For example, iron ore and bauxite.
Metallic minerals are of two types: (a) Ferrous and (b) Non-ferrous.
Ferrous minerals contain iron ore, manganese, and chromites. Most of the Iron and steel industries and heavy industries depends on this mineral.
Non-ferrous minerals do not contain iron but may contain some other metals like gold, silver, copper or lead.
Non-metallic minerals do not contain metals. For example, limestone, mica, gypsum, coal, and petroleum.
Mining, drilling, and quarrying are the three extraction methods of minerals.
Mining is the process of taking out minerals from rocks buried under the earth’s surface.
