The copper Leaching, Solvent Extraction and Electrowinning circuit (LX–SX–EW) is one of the most effective processes for extracting copper from low grade ores. This work focuses on the liquid–liquid extraction SX sub-process, since many difficult to handle operational problems within LX–SX–EW circuits are related to SX malfunction.

The steps are as follows: 1) LEACH. Low grade copper ore is leached, producing solid waste and copper PLS. 2) EXTRACTION. The copper PLS is sent for extraction where the copper is loaded into the organic phase, leaving a copper-barren leach liquor (raffinate) to be recycled back to the heap leach. 3) STRIPPING.
