For copper, the "typical" SX-EW plant producing copper cathode from bioleaching has been on the order of 10,000 t/year, with some multiples of this scale observed. The recently commissioned IBBCo copper concentrate bioleach operation in Iran appears to be the largest plant in operation at this time, producing 50,000 t/year of …

Copper minerals generally occur as oxides or sulfides. These require different treatments for extraction of the metal. The oxides are exposed to acid in a heap leach; this liberates the copper ions and the resulting solution is then sent to the solvent extraction (SX) process followed by electrowinning (EW) of the copper.

During the last two decades the copper leaching, solvent-extraction and electrowinning (LX/SX/EW) process has become an important option in the production of copper from low-grade oxidized ore. LX/SX/EW copper production has grown rapidly during the last decade and further growth can be expected. (Jenkins et al., 1999; Kordosky, 2002)

Fig. 1 shows a possible layout of a SX–EW process used to recover copper from solutions produced by ore leaching. The process of Fig. 1 consists of two extraction stages followed by a stripping stage in closed circuit with an EW unit. The pregnant solution from the leached ore piles is mixed in a first mixer–settler unit with an organic phase …
