> Solvent Extraction A broad range of solvent extraction test programmes can be carried out at Core. Core Group's experience and capabilities include simple benchtop studies involving 'shake out tests' through to operation of SX pilot plants of various sizes and levels of complexity.
Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized.
· Outotec has been awarded a contract by La SinoCongolaise des Mines SA (hereafter as Sicomines), a jointventure formed by companies from China and the Democratic Republic of Congo, for the delivery of copper solvent extraction technology to Sicomines' project near Kolwezi in the Democratic Republic of Congo.
•Solvent extraction, also called liquidliquid extraction (LLE) and partitioning •Immiscible liquids are ones that cannot get mixed up together and separate into layers when shaken together. These liquids are usually water and an organic solvent.
· A method for the recovery of copper from a copper containing source by a solvent extraction electrowinning process wherein a copper containing pregnant leach solution is extracted with an immiscible organic solvent to form a copper loaded organic stream, the loaded organic stream is stripped by an aqueous stream to form a copper rich electrolyte stream and the copper rich .

· Sicomines to use Outotec's copper solvent extraction technology 02 Jun 2020 Finnish technology company Outotec has secured a contract from La SinoCongolaise Des Mines (Sicomines) to deliver copper solvent extraction technology to Sicomines' project near Kolwezi in the Democratic Republic of the Congo (DRC).
Once solvent extraction has proved to be a costeffective way of purifying and concentrating copper from leach liquors, copper producers have begun to consider leaching as a much larger source of copper (Kafumbila, 2015). The solvent extraction of copper consists of .
SXEW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SXEW reactor, the first process to take place is solvent extraction, which involves
Today, more than 13% of all "new" copper is produced from leachates, which are normally concentrated using solvent extraction (SX) and stripped of their copper content by conventional electrowinning (EW), the socalled SXEW process.
copper extraction from to % and with LIX 84 IC the percent copper extraction increases from to % with the increase in LIX 84 IC concentration from 10 to 40% at organic/aqueous ratio of 2:1, room temperature and mixing time 5 minutes. Thus Acorga M 5640 appears to be a better solvent than LIX 84 IC for copper extraction.
· Solvent extraction with LIX 973N for the selective separation of copper and nickel. ... It was observed that neither copper nor nickel extraction is sensitive to temperature and equilibrium pH, however nickel extraction equilibrium is reached at a longer contact time ...
The solvent extraction of copper(II) from nitrate medium with lauric acid (HL) at 25°C is studied as a function of various parameters: pH, concentration of lauric acid and the nature of solvent. The solvent effects on the extraction of copper(II) using polar and nonpolar solvents are treated.
