Reserve Definition: Converts an ore resource to a mineral reserve. India has large deposits of bauxite ore. The Government is aiming for an adequate and effective legal and institutional framework mandating zero waste mining as the ultimate goal and a commitment to prevent sub-optimal and unscientific mining. The population growth continues upward and the supply of resources continues to diminish. The disruption of land otherwise suitable for agricultural, urban or recreational use; the deterioration of the immediate environment through noise and airborne dust; and the creation of ore of the most dangerous environments for workers and potentially hazardous for the public are all environmental problems associated with mining. The long-term disposal of radioactive wastes is still an unresolved problem.
Answer: The given statement can be justified by the following arguments. Mining: This step is the actual excavation of minerals from the ground. The need of the hour is to conserve the present resources. How is energy a basic requirement for the economic development of the country? The lure of large revenues, generous financial assistance, finished products, arms and other necessities force poor countries to sell their mineral wealth at a cheap price. Usually, this simply involves dumping the wastes İn piles at the surface next to the mine workings. Why is energy required for all activities? Underground mines need extensive hoisting systems to transport the minerals, which also require energy.
Gold, silver, diamond, iron, coal, and uranium are just a few of the vast array of metals and minerals that are obtained by this process. Acid mine drainage formed by dissolution of pyrite dissolves more pynte, thus accentuating the effects. How do minerals occur in sedimentary rocks? The first is disposal into underground caverns or voids left from mines. Explain any three methods of conservation of mineral resources in India. Why is there a pressing need to use non-conventional sources of energy in India? It is high time now that we should seriously think about conserving them. People can conserve mineral resources by utilizing renewable resources.
The minerals are limited in quantity and they can be vanished 2. When you travel for a short distance, use a bicycle 5. Answer: In igneous and metamorphic rocks, minerals may occur in cracks, cervices, faults or joints. The other states like Gujarat and Goa have also manganese ores. The total volume of workable mineral deposits is an insignificant fraction i.
Health and Safety: Mining can be very safe, but often it is extremely dangerous. Gold from the American River! We have moral and social obligations conserve them, avoid their misuse and wastage a: preserve them for use in future. Throughout the world, forest fire is common and in most cases they were begun by man. Most of the chemicals are released into nearby water bodies, and are responsible for water pollution. The states like Orissa, Uttar Pradesh, Rajasthan, Madhya Pradesh, West Bengal, Gujarat, Tamil Nadu etc have ores of lead.
Thinkof all the ways we use natural resources. Similarly, any forested land which has been destroyed by fire or mining activities should be reforested. Besides all this, fresh afforestation programmes should be started. Tin and copper mines were necessary for a Bronze Age; gold, silver, and gemstones adorned the wealthy of early civilizations; and iron mining introduced a new age of man. Avoid use and acceptance of minerals which are not essential. Answer: The most abundantly available fossil fuel in India is coal.
Currents, sedimentation patterns and erosion patterns are changed by ocean mining operations. Similarly more reliance should be placed on the exploitation and utilisation of such mineral resources which are renewable and are in plenty. Goa has also deposits of iron ore. As per National Mineral Policy 2008, conservation of mineral shall be construed not in the restrictive sense of abstinence from consumption or preservation for use in the distant future but as a positive concept leading to augmentation of reserve base through improvement in mining methods, beneficiation and utilisation of low grade ore and rejects and recovery of associated minerals. Land Pollution : Land pollution can be rectified through standard reclamation efforts;however it must be made mandatory to reclaim abandoned mines. Old underground mines can be used as storage areas for grains, seeds, burial of nuclear wastes, and truck parking. Burning fossil fuels The burning of fossil fuels in automobiles, power plants and heating systems creates air pollution.
These actually save power andresources. Acid Mine Drainage: Acid mine drainage is currently treatable with several different chemicals that neutralize the acid: calcium carbonate, calcium hydroxide, calcium oxide,sodium carbonate, sodium hydroxide, and anhydrous ammonia. Natural resources are resources we get from nature example: fossil fuels, water, minerals. Strip mining waste can be used in reclamation, but an alternative method of disposal must be found for underground mining operations and most kinds of open pit mining. Explain any three factors affecting the economic viability of a reserve of minerals. Answer: The given statement can be justified by the following arguments.
An important way to conserve some minerals is by substitution, when the plentiful resources are substituted for scarce ones. In most mines, ore extraction and mine development involve drilling and blasting, and removal with mechanical diggers onto underground railway cars or dump trucks that reach the surface through a shaft. How do minerals occur in igneous and metamorphic rocks? It is also used in the manufacture of medicines. Conventional resources include fire wood, cattle dung cake, fuel minerals like coal, petroleum etc. They do not care about the environment; their sole value is profit. How is energy an indispensible requirement of our modern life? Like other natural resources, mineral deposits are unevenly distributed around on the earth. Some metals are irrecoverably lost to the environment due to mishandling, corrosion, wear and tear.
Heavy metals, such as sulphur dioxide, may be polluted into the air by unsafe smelter operations with insufficient safeguards. Organisms in these water bodies do not have enough water for their survival. The mineral materials may be used as such or used for extraction of elements. Further waste occurs at the sawmill. This practice has been adopted by many countries, both developed and developing.
