Answer:
Industrial minerals are non–metallic minerals used in a range of industrial applications including the manufacture of chemicals, glass, fertilisers and fillers in pharmaceuticals, plastics and paper. Industrial minerals include salt, clays, limestone, silica sand, phosphate rock, talc and mica.
Answer:
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.
The process of mining includes two methods: (a) Open cast mining, (b) Shaft mining
Deep wells are bored to take minerals out and this process is called drilling.
In the process of quarrying, minerals that lie near the surface are simply dug out.
Mineral based industries are the backbone of industrial development of a nation.
Mining needs cheep labour and resources to extract it off.
