SX-EW (solvent extraction and electrowinning) are distinct metallurgical unit operations that recover high purity metal from leachate solutions. Solvent extraction is used to concentrate materials in an organic solution, while electrowinning is used to recover these pay elements.
The aim of including SX in copper refinery plant is removal of copper that bringing with O2 and constructed. In these plants EW is better than SX to removal of copper oxide. The amount of bleeding should be calculated according to amount of O2 in anode.
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined.
Solvent extraction followed by electrowinning (SX–EW) is an economical option for the processing of low-grade and oxidized copper ore. Phenomenological models were developed to simulate the copper SX and the EW processes. The two models were linked together to make a SX–EW simulator.
Solvent extraction (SX), sometimes called liquid ion exchange, is used to selectively concentrate and purify a desired element after it has been dissolved in an aqueous solution. The liquor is contacted with an organic solvent, chosen for its selectivity towards the element or elements of interest.

The Kinsevere Copper Extraction Plant described in this report is a brown-field site located in southern part of the Katanga Province in the Democratic Republic of the Congo (DRC), approximately 20km north of the provincial capital, Lubumbashi.
The Dual Media SX filters are automatically controlled in service, organic recovery and backwash with a PLC in a NEMA 4X housing to protect it from the environment. Custom controllers can be engineered and built to any specification for single unit or multiple unit control.
Mopani Copper Mines Plc was originally part of Zambia Consolidated Copper Mines Limited (ZCCM), and was state-owned until its privatisation in 2000. On 1 April 2000, Mopani purchased the ZCCM assets at Mufulira and Nkana, consisting of the underground mine, concentrator, smelter, refinery and cobalt plant, from the government.
In the extraction section of solvent extraction the mass of copper lost from the leach solution in a period of time is equal to mass of copper gained by the organic phase in that same period of time. Example: 750 m³ / hour of PLS having 6.71 g/l Cu is treated in a copper SX plant with 2 extraction stages and 2 strip stages with an organic ...

Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-
be calibrated to match the performance of commercial SX plants, which allows the production engineer to accurately determine the impact that changes in PLS chemistry, reagent concentration, reagent blend and/or circuit configuration will have on copper recovery. Final Copper Cathode product bundled, weighed and ready for shipment.
Extraction tank, as the key equipment of SX, its design is very important for air control, especially the design of the mixer's rotational speed and its diameter. When the mixer's
SX-EW is a two-stage hydrometallurgical process that first extracts and upgrades acid-soluble copper from low-grade waste dumps, using dilute sulphuric acid, followed by extraction and upgrading of the leached copper solutions into an organic solvent mix containing a chemical that selectively reacts with and removes the copper.
