Copper processing Ores Britannica

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   Substance flow analysis (SFA) is a systematic assessment of stocks and flows of noxious or specific elements within a predefined temporal and spatial system boundary The SFA originates from the material flow analysis (MFA) ( Brunner and Rechberger, 2004 ) Both the MFA and SFA obey the law of mass conservationSubstance flow analysis of copper in production stage in

Estimated Water Requirements for the Conventional

  the amount of water required to process copper sulfide ore through a conventional crushgrindflotationconcentrate circuit ranges from roughly 15 metric tons (t) to about 35 t of water to process 1 t of ore [Wels and Robertson, 2003, 2004; Misra and others, 2005; Wills and NapierMunn, 2006; Chilean  The results show that using nondesalinized seawater in copper ore processing can help prevent AMD due to the buffering effect of seawater and the protection coat formed by oxyhydroxide and/orFlowchart of the copper production from sulfide minerals
