Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest ...
Others have barely any gold at all but may have plenty of molybdenum. Large Size, Low Grade – Porphyries typically have 100 million to 5 billion tonnes of ore with a lower grade (0.2% to >1% copper). It is the size of these deposits that allow for bulk mining and economies of scale. Long Mine Life – The size of porphyry systems usually mean ...

Hydraulic mining uses water power to fracture and transport a bench of Earth or gravel for further processing. Hydraulic mining is used for placer deposits of gold, tin, and other metals. Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines).
steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.
The gold rush bolstered the world economy and put wealth into the hands of many opportunistic investors, but rapid industrial gold mining comes at a steep cost to the environment. As it stands, traditional methods of mining gold …
The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
