Question

Why is it necessary to conserve mineral resources? Explain any four ways to conserve mineral resources.

Answer 1

Hint:Minerals are broadly defined as solid chemical compounds with a specific chemical composition with a specific structure that occurs naturally in the earth’s surface. Mineral resources contribute to about 95% of the energy used by mankind, 80% of industrial raw materials and 70% of raw materials for agricultural production. Most minerals are inorganic which means that they do not contain carbon-hydrogen molecules except for some minerals that contain some organic elements like gold, silver, diamond, and sulphur.

Complete Answer:Mineral resources are non-renewable which means that they have a limited supply and take a very long time to replenish. Due to the rapidly increasing consumption rate for mineral resources, once exhausted they will take a very long time to form naturally in the earth’s crust which is why they have to be conserved and used sustainably. Some methods of conservation of mineral resources include:
-Using alternative renewable substitutes of such mineral resources.
-Reusing, recuperating and recycling minerals.
-Developing such technology that low-grade ores can be used profitably.
-ensuring minimal wastage during mining.
-minimising the negative environmental effects that mining has.
-exploring new areas where minerals can be mined.

Note: Mineral resources are divided into two major categories—metallic and non-metallic minerals. Metallic minerals are further divided into ferrous and non-ferrous. Examples of ferrous minerals include chromite, iron ore, manganese, etc. Examples of non-ferrous minerals include lead, silver, gold, copper, zinc, etc. Examples of non-metallic minerals include limestone, marble, gypsum, sand, etc.
