People extract valuable minerals from the lithosphere. Rock that contains high concentrations of valuable minerals are called ore. Various methods are used to locate potential sites for mining. Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining).Mining and concentrating. The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified.In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).
