Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in an ore can …

The extraction of copper minerals from unpayable ores containing a low concentration of copper in the ore (oxide, mixed ores, and secondary sulfide ores) can be affected by the leaching of ground ore followed by solvent extraction and electrowinning. This technology is applied in a number of large copper productions, including ndida ...

validated through large scale trials and process was designed for concentration of the copper ore sample. The results indicated that it was possible to obtain copper concentrate with 29.25% Cu with copper distribution of 81.7% by two stages of cleaning of rougher float. Third stage of cleaning flotation further

Burns and Grimes (1986) reported pre-concentration of a copper ore by screening at the Bougainville copper plant operation. Based on detailed recovery-size-yield data collected from the Newcrest Telfer operation, Bowman and Bearman (2014) reported a potential application of coarse waste rejection through size-based separation for copper production.
