PLEASE ANSWER IT FASTLY ............What do you mean by Mining and Quarrying

The process of taking out minerals from rocks buried under the earth's surface is called mining.
Minerals that lie near the Earth's surface are aimply dug out,by the process known as quarrying

g extract a wide range of useful materials from the ground such as coal, metals, and stone. These substances are used widely in building and manufacturing industry, while precious stones have long been used for adornment and decoration. Mining and quarrying involve investigating potential sites of extraction, then getting the required material out of the ground, and finally processing with heat or chemicals to get out the metal or other substance of interest. All these operations may use large amounts of water.
Mining and quarrying can be very destructive to the environment. They have a direct impact on the countryside by leaving pits and heaps of waste material.

The extraction processes can also contaminate air and water with sulfur dioxide and other pollutants, putting wildlife and local populations at risk. More careful use of natural resources, including recycling, and also restoration efforts after mining and quarrying can help limit these environmental impacts.
Historical Background and Scientific Foundations
People have always extracted useful materials from the ground. The Stone, Bronze, and Iron Ages were underpinned by knowledge of how to obtain these materials. Archaeological studies have shown evidence for copper mining in Africa around 6,000 years ago and, a little later, in ancient Egypt and North America. Meanwhile, the Romans developed many mining techniques to make the process more efficient. Today practically every manufactured item contains material that has been mined or quarried.

Mining involves taking an economically useful material from the ground. Substances that are mined include ores, coal, evaporites, and precious stones and metals. Quarrying is the cutting or digging of stone, and related materials, from an excavation site or pit and it usually leaves behind a large hole in the ground.

An ore is a deposit containing an economically viable amount of a mineral, which itself is a crystalline inorganic compound, usually containing a metal. It is the metal that is of value. The main groups of minerals that are mined are oxides, sulfides, and silicates. Economically, the most significant metals are aluminum, manganese, copper, chromium, and nickel.
The evaporites are materials that are deposited in the ground from evaporation of chemical solutions. They include rock salt, used for culinary purposes and in water softening, and gypsum, which is used to make plasterboard. Substances like diamond, precious metals, and stones are always in great demand for decorative purposes, including jewelry. Meanwhile, gravel, clay, sand, and limestone are quarried in vast quantities for use in building materials like concrete, cement, and glass. Crushed stone from quarries is used in large amounts to build roads. A mile of a motorway could require nearly a quarter of a million tons of crushed stone.

Sulfur deposits are mined mainly to make sulfuric acid, which is a mainstay of the chemical industry.
Mining and quarrying involve three distinct stages. First there is exploration and assessment to see whether a resource is worth exploiting. This might involve a certain amount of drilling into the ground. Then the substance is extracted by whatever technique is most appropriate to its location. This is often dictated by the depth of the resource under the surface. Open pit and shallow strip mining are commonly used to extract resources up to 600 ft (180 m) below ground. The mining process removes the source and the rock and soil, known as overburden, on top of it. The overburden is stacked up into a so-called spoil heap close by. Deeper resources will be extracted by underground mining that can go to about 8,000 ft (2,440 m). Beyond this, temperatures increase to a level that makes mining impracticable.

Rock removed to create tunnels for mining is generally added to the spoil heap. Finally, the ore or other resource must be processed to extract the metal or material of interest. This usually involves some kind of heat or chemical treatment. For example, smelting is a common form of processing and involves roasting an ore to release the metal it contains.
