Mineral Resources

so our next topic is Mineral Resources Minister naturally occurring chemical compounds farm to farm to inorganic processes under the crust of the earth the presence in the earth crust is because of the many geological processes which are taking place for a long period of time the distribution of these metals are uneven and they are distributed unevenly all over the earth India is rich in minerals such as iron aluminum manganese chromium limestone dolomite and mica minerals are non-renewable that means once they have finished and there will not be anything else for use and they are also responsible for the economic and industry development of the country minerals are divided into three part one is metallic mineral nonmetallic minerals and film enters the Earth's are mined metallic minerals are journey from generally available in the form of compounds like oxides like chlorides like sulfates so they need the ores need to be purified before cooking before getting the pure metals so that is the metallic minerals about eleven metallic metals are produced in India some of the principal metallic minerals are iron or iron lead zinc copper manganese etcetera nonmetallic minerals are the minerals which can be easily mined from the from the earth itself and they don't need any chemical treatment for that these minerals are used as in their natural occurring States most important minerals are like diamond marble granite salt and mica of all the minerals found in India about are nonmetallic minerals and principal nonmetallic minerals found in India are asbestos from dolomite and gypsum and the fuels like coal petroleum and natural gases are kept in another group that is fuel mineral so they are so the minerals that are utilized as use unknown as fuel minerals no effect of an effect of extraction of minerals on environment first of all it reduces the soil fertility and increases the soil erosion it also gives increases the deforestation that means cutting of the forest it generates large amount of waste films from spent smelters damages forests and spreads pollution pollution of air water and land it causes ground subsidence and groundwater pollution it also results in removal of natural ecosystems and creation of trenches and open pits earthquake and volcanic area events are very frequent here mining also leads to occupational health hazards - - including diseases such as asbestosis silicosis black lung disease lung disease destruction of natural ecosystem and creation of ditches and open pits so these are some of the effect of extraction on environment now what are the environmental impact of - first of all mining is of to tack when is underground mining and under this surface or opencast mining so underground mining subsidence and pollution of aquifer excision is like flooding and collapse of a common causes so serves health problems for workers more chances of earthquakes on the other hand for the surface or opencast mining destroys all vegetation in the area pollutes the landscape with the dust after mining large craters are left behind when hills that act as watersheds are mined away the water table goes down processing of the mines minerals pollute water bodies also the waste material left behind as unstable and dangerous heaps social impact of mining first of all loss of land livelihood and even cultures increased health risk due to contamination of natural resources such as land and water change in population dynamics worker often come from outside threats to mineral sources so one day these mineral resources will finish and what are the main threats to the Mundell resources first itself is mining secondly disturbance to the mental layer which may lead to the earthquake drawing of the land next is the deforestation loss of loss of biodiversity the acid main mine during the acid mine drainage of acid to extract process which leads to a mixture of acids in soil in aquifers so if people are using acid to good extract the things then these acids can go into the soil and aquifer naturally the loss of marine life due to high spill over the sea surface while extracting oily what is the state of mind in and minerals in India India produces as many as minerals and mine the metals and minerals about this % of mining in India is for coal India has over , legal minds but also we are having lakh , in legal minds in the country over million people are employed in these industries and mining has adversely affected the biodiversity ecosystem local culture and community about million have been displaced from mining areas and % % of them have not received proper compensation tribals were worst-affected so that was all about the natural resources member you
