8/7/2019 A mineral is a naturally occurring inorganic solid with a specific chemical composition and crystalline structure

1/1

xtracted from the earths crust.

iscovery and exploitation of rich resources can prove an asset for a developing country like india.

here are four Types of minerals are

ne type is metallic and three are non-metallic.

1) Metals likeIron, copper, aluminium, etc.2) Industrial minerals like lime, potash, etc.3) Construction Minerals like sandstone, gravel, etc.4) Energyminerals like uranium, etc.

USES OF MINERALS

1) For development of industrial plants and machinery.2) Coal, lignite and uranium are used for generation of energy.3) Used in defence systems like weapons and armaments.4) In communication system like cables, telephone wires, etc.5) Used in many medicines.6) Gold, silver, platinum, diamonds are used as jewellery.The minerals are extracted from the earths crust with the help of a technique called mining.

Extracting minerals from the earth and processing them produces enormous environmental damage . It

pollutes the soil, air and water. Destroyed land due to mining is called mine spoil. Mining produces 3/4th

of

all waste

TYPES OF MINIG ARE:-

1) Surface strip mining:- In this the topsoil is scraped off. The overburden, the rock lying above the mineral is

stripped off. This leads to unsightly slag heaps and large holes in the ground.

2) Underground mining:- In this type of mining caves and tunnels are made for the extraction of the ore.

ILL EFFECTS OF MINING:-

1) Mining produces as much as soil erosion as all earths rivers combined.2) Air pollution from the mineral industry has made hectares of cultivable land unfit for the use.3) People residing near uranium mine in Jharkhand are exposed to nuclear hazards.4) Underground fire in jharia coa l mines has forced displacement of local people.5) River pollution is cause of concern due to iron ore mine in Karnataka.6) High sulphur contamination of ground water is taking place in north eastern coal fields of assam.

s minerals are finite in number so there is a need of conserving them and using them in a best possible way to

inimize their wastage and maximize their use. Here reuse and recycling of minerals plays a very vital role by not

nly helping in conserving them but by permitting us to reduce envir onmental damage from their extraction and

rocessing.

he main motive of todays production industries should be The use of previously used materials for new

urposes

ike glass, aluminium cans,etc. This will consume less energy and the cost of producti on would be minimize.

onservation:-

1) Conservation of minerals should be encouraged by producing and using products that last for a long timeand so do not need to be replaced often.

2) Substituting something else for a mineral like synthetic polymers like pvc , fiberglass, polyester, etc.So mineral resources are very important for the survival of the human -race and we should contribute our bit

towards their conservation and efficient usage. THAN KYOU.
