Surface Mining Methods and Equipment

Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining

Note of Mining methods by DEEKSHITH GODUGU

UG MINING METHODS BORD PILLAR Method • Coal deposits are mined by cutting a network of 'roads' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine. LONGWALL Method • It involves the full extraction of coal from a section of the seam or 'face' using mechanical shearers to cut and remove the coal at the face.

Geochemical Prospecting

Mineral deposits represent anomalous concentrations of specific elements, usually within a relatively confined volume of the Earth's crust. Most mineral deposits include a central zone, or core, in which the valuable elements or minerals are concentrated, often in percentage quantities, to a degree sufficient to permit economic exploitation.

Mining

Mining is the extraction of minerals and elements of economic interest from the earth's surface. As the demand for natural resources increases, the amount of material in mineral deposits decreases. An increase in price of these materials allows companies to continue to profit from mining deposits with lower ore grades.
