Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile Escondida mine and Indonesia Grasberg mine. These produce many millions of tonnes of copper ore per year.

EHMs Ore Reserve Estimate at 30 June 2010 is 88 million tonnes at a grade of 1 copper, 0.5 grams per tonne gold and 23 ite. In 2010, EHM produced 74,595 tonnes of copper in concentrate and 91,259 ounces of gold in concentrate.

Optical sorting and lasers are very well suited to the detection of ores with different colours, such as copper oxide, or crystalline structures in quartz. By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi mobile form and consists only of crushers, screens, belts and

Copper Rand was the principal source of ore for Campbell Mines when it terminated operations. Historically it was also the biggest source of ore from the Lac Doré camp. The current resources are in two areas: the CR5000 zone and the Hanging Wall zone. The majority and higher grade resources are in the CR5000 zone and these are the resources that Doré Copper could target in a latter year of a

Molybdenum moly is often produced as a byproduct of copper mining. Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst. As markets need copper and moly, their ores are separated, concentrated, and sold separately. This separation and concentration of copper and moly is called the copper moly flotation circuit

Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores primary copper production. Davenport, et al, noted in 2002 that even then 80 of global primary copper production was from copperironsulfur minerals and that the vast majority of these were treated by smelting.
Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters
Ore at the Black Mountain Mine is more copper rich, in contrast to the other deposits to the east which are all more zinc rich. Thisprises two superposed massive sulphide bodies namely the thicker Upper Ore Body UOB and a thinner Lower Ore Body LOB. Both ore bodies, which also carry disseminated sulphides, are hosted in the banded iron formation. The iron formation horizons
These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2 and 5 copper, with gold contents ranging from 0.1 to 3 grams per tonne parts per million.
The process used to treat sulfide copper ores begins at the mine site, where the copper bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing
