Ecton Mine, Peak District Mining Manifold Valley, Copper

The ore yielded as much as 60% copper which is a very high grade indeed, therefore making the owner very rich! Many copper ores that are mined today yield only 2 – 3%. This mining boom period lasted for 30 years between 1760 and 1790 and was the source of money used to build Buxton’s Crescent and Stable Block (the latter was later to become the Devonshire Royal Hospital).

Zambia’s Advanced, World-Class Copper Smelter in Action

That’s why most copper mines in the world limit their mining activities to extracting copper ore from the ground and taking it through the first stage of processing until it emerges as copper-sulphide concentrate – a greyish-black powder that contains around 25% copper. The concentrate is then transported to the nearest smelter to be turned into finished copper, at an agreed smelting fee.

5. The technology of mining and metallurgy

Historically, mining activity began and expanded with the exploitation of underground deposits, usually of high grade ore. For example, the first copper deposits to be exploited were small, stratified concentrations of high quality ore, with from 10% to 15% metal content, but later, the growth in world demand led to the exploitation of much larger open-pit mines with lower grade deposits ...

Copper Flotation - Mineral Processing Metallurgy

19/03/2017  Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate. It ...

Copper Mining and Extraction Sulfide Ores

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.
