·Growing role of solvent extraction in copper ores processing 31 • solvent extraction in which the aqueous pregnant leach solution PLS is vig orously mixed with an organic solvent selectively
·Copper solvent extraction from chloride solution has been studied using four LIX® extractants LIX84 I LIX612N LV XI 04003 and LIX984N from BASF with respect to copper extraction as a function of pH and A/O ratio and behavior of the impurities At a pH below the copper extraction increased quickly with increasing pH while at a pH
Solvent extraction is a simple process in which oily waste and solvent are mixed in an appropriate proportion to ensure adequate miscibility of oil in solvent while most water and solids are rejected as unwanted impurities that may be removed by gravitational settling or centrifugation The oil and solvent mixture can then be separated by distillation Hu et al
·The studied copper solvent extraction process consists of four units three for extraction and one for stripping as presented in Fig inputs of the process are pregnant leach solution series and parallel flow rates F PLSS and F PLSP pregnant leach solution copper concentration c PLS lean electrolyte flow rate F LE lean electrolyte
·It has been explained in an earlier talk that solvent extraction in the copper industry is used to convert impure and frequently very dilute copper solutions into very pure and concentrated solutions from which pure copper can be extracted by a variety of means usually electrochemical
·The solvent extraction of copper from a sulfate chloride solution containing seawater and/or sodium chloride was studied using the commercial extractants LIX 984N and Acorga M5910 The effect of
·The second aqueous phase is pure and concentrated Stevanovic et al 2009 Once solvent extraction has proved to be a cost effective way of purifying and concentrating copper from leach liquors
·Solvent extraction is a purification method that utilizes the immiscibility of liquids to separate different species between two liquid phases usually an aqueous phase and an organic solvent phase The transfer of species for example metal ions from the aqueous phase to the organic phase is aided by extractants forming lipophilic complexes
Pure copper metal is mostly produced from these ores by concentration smelting and refining About 80% of the world s copper from ore is produced by concentration/smelting/ refining of sulfide ores The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide and chalcocite ores
