During the copper recycling process, it saves between 85-90% of energy resources as opposed to mining the earth for new copper ore.; Worldwide supply of copper is about 8.1 trillion pounds, but we have only mined about 13.6% (1.1 trillion pounds) throughout history.

Copper ore density separations by float/sink in a dry sand

Jun 10, 2013 For the ARC-1 ore, one could conceive of a separation at 2350 kg/m 3, which would remove about 50% of the feed ore mass as gangue which contains very little copper. Based on these observations, target separation point densities for the dry dense medium separations have been chosen as 3300 kg/m 3 for the EH ore and 2350 kg/m 3 for the ARC-1 ore.

Olympic Dam Copper-Uranium Mine, Adelaide, Australia

After treatment by flotation, the finely-crushed ore is leached with sulphuric acid to dissolve uranium and any remaining copper. The leach liquor is processed in the solvent extraction plant to separate the residual copper and uranium streams. Copper is recovered by electrowinning and uranium converted to yellowcake and calcined uranium oxide.

How to Process Copper Lead Zinc Ore with Gold and Silver

Apr 27, 2016 The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.
