Patent number: 8012318Abstract: A system and process for recovering copper from a copper-containing ore, concentrate, or other copper-bearing material to produce high quality cathode copper from a leach solution without the use of copper solvent/solution extraction techniques or apparatus. A process for recovering copper from a copper-containing ore generally includes the steps of providing a feed stream containing comminuted copper-containing ore, concentrate, or other copper-bearing material, leaching the feed stream to yield a copper-containing solution, conditioning the copper-containing solution through one or more physical or chemical conditioning steps, and electrowinning copper directly from the copper-containing solution in multiple electrowinning stages, without subjecting the copper-containing solution to solvent/solution extraction prior to electrowinning.Type: GrantFiled: April 29, 2010Date of Patent: September 6, 2011Assignee: Freeport-McMoran CorporationInventors: John O Marsden, Robert E Brewer, Susan R Brewer, Joanna M Robertson, David R Baughman, Philip Thompson, Wayne W Hazen, Christel M.
