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.
