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

Sep 26, 2019 · Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80% of global copper production is extracted from sulfide sources

Most copper produced is extracted from sulfide deposits. Chalcopyrite is the most important ore of copper. Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step

Jan 25, 2020 · The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels
