Question

what is Mineral? Mention the three main processes of mineral extraction.

Answer 1

$\mathcal{\huge{Hii}}$
Mineral is a naturally occurring inorganic substance. Eg:- Copper, iron etc.

Three process are :-

1) Mining :- In this process metals are extracted by diging the earth

2)Drilling :- in this narrow but deep drills are duged to extract the mineral.

3) Quarring :- in this metals are extracted for building process.

Answer 2

A naturally occurring substance that has a definite chemical composition is known as a mineral.

Minerals are broadly classified into three types: Metallic, Non-Metallic and Power Minerals.

Minerals can be extracted by Mining, Drilling and Quarrying.

(a) Mining: The process of taking out minerals from rocks buried under the earth's surface is called mining, Drilling and Quarrying.

    (i) Open Cast Mining: Minerals that lie at shallow depths are taken out by removing the surface layer is known as "Open Cast Mining".

    (ii) Shaft Mining: Deep bores, called shafts, have to be made to reach mineral deposits that lie at great depth; this is known as "Shaft Mining".

(b) Drilling: Petroleum and natural gas occur far below the earth's surface. Deep wells are bored to take them out; this is called "Drilling".

(c) Quarrying: Minerals that lie near the earth's surface are simply dug out by the process known as "Quarrying".
