Mineral dressing = Orebeneficiation The first process most ores undergo after they leave the mine is mineral dressing processing, also called ore preparation, milling, and ore dressing or ore beneficiation Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate

explanation "Run-of-mine" ore is a mix of valuable minerals and worthless rock in which each ingredient is priced separately Run- of-mine ore is treated in the dressing plant and processed into different concentrates Where the ore contains more than one metal of value, separate concentrates of, for example, copper, zinc, and lead are produced

About 80 of primary copper production comes from low-grade or poor sulfide ores After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods Generally, copper extraction follows the sequence see Figure below: 1 Beneficiation by froth flotation of ore to give copper concentrate

Triggering many mine closures However, the copper ore in North Wales were worked out within 20years and during this time Cornish miners had made huge improvements in pumping technology and working methods During the early years of the 19th century Cornwall had once again become the top copper ore producer in Britain, and the world

The greatest known reserve of copper ore in one body is the deposit at El Teniente mine in Chile Many lesser deposits are being exploited, such as those in Canada, China, Australia, and Europe Mining For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit These deposits form a mineralized package that is of economic interest to the miner Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining In a few instances, however, leaching takes the place of concentrating, smelting, and refining At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger

Reasons for Designation For several millennia the south west peninsula has been one of the major areas of non-ferrous metal mining in England, its more important and prolific products including copper and tin, along with a range of minor metals and other materials, notably arsenic, which occur in the same ore bodies

The ore is removed from the ground in either open pit or underground mines Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore Open-pit 90 of ore is mined using the open pit method Ores near the surface can be quarried after removal of the surface layers The ore
