Many mining companies are following the following steps to extract gold from the earth surface. As technology improves more and more mining techniques are being discovered to make the work simple. Literature Survey: In India lot of government agencies are taking out verification surveys on gold mining. Among those agencies there are two main agencies….
The process of mining the earth and finding the metals, minerals, etc and again making the earth to return back to its original state consists of different steps. Generally, mining techniques can be broadly classified into two types, they are Surface Mining and Underground Mining. In pre-historic period, when the people had found metals like…
The metal ore mining industry segment covers the extraction of metal ores, primarily gold, silver, iron, copper, lead, and zinc. These naturally occurring minerals have a variety of industrial purposes: gold and silver are primarily used in jewelry and high-end electronics, iron is used to produce steel, copper is the main component of electrical wiring,…
The oil and gas extraction segment produces the petroleum and natural gas that heat homes, fuel cars, and power factories. Petroleum products are also the raw materials for plastics, chemicals, medicines, fertilizers, and synthetic fibers. Petroleum, commonly called crude oil or just oil, is a liquid formed under ground from the decay of plants and…
The coal mining industry segment produces coal, a fossil fuel that is used primarily for electric power generation and in the production of steel. Like oil, coal is formed over millions of years from plant and animal matter, but unlike oil, coal is a solid, and therefore miners must go into the earth to recover…
Opal: Opal has been a mystery for centuries. No two opals look alike. The word “opal” was derived from a Greek word opallos, meaning ‘to see changes of color’. Opal is derived as a precious gemstone which is formed from non-crystalline silica gel. It consists of 6 to 10 per cent water and small silica…
Platinum: Platinum is a material which is very rare and the cost of gold is double than gold. In igneous rocks platinum is formed and these rocks also have iron and magnesium. Along with other materials like copper and gold, Platinum is also found in thin layers. Using surface and underground Platinum is mined. Due…
Gold mining consists of the processes and techniques employed in the removal of gold from the ground. Earlier gold was mined using different methods like Panning, cradling, dry blowing, shaft mining, Puddling and dredging. Nowadays open cut mining and underground methods are used for gold mining. Panning is one of the oldest techniques of separating…
Magnesium is the third most used metal, following iron and aluminium. Magnesium derives its name from magnesite, a magnesium carbonate mineral, and this stone in turn is told to owe its name to magnesite dumps found in Magnesia, a region in the antique Greek region of Thessaly. The British chemist Humphry Davy is said to…
