The price of copper is increasing as supplies of high-grade ores start to run out. The mineral covellite (CuS), found in low-grade ores, is a possible future source of copper. (a) When copper is extracted from covellite, a reaction occurs between copper(II) sulfide and nitric acid to form a dilute solution of copper(II) sulfate.

Extracting metals (boardworks) - [PPT Powerpoint]

16. Boardworks Ltd 200616 of 27 Copper is not very reactive and can occur native but it is rare to find pure copper. Usually, it is found combined with other elements, such as in the ore malachite. Copper is an excellent conductor and does not corrode quickly. These properties make it a good material for wiring and plumbing.

Innovations: Introduction to Copper: Mining & Extraction

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
