  • Solvent extraction of copper from sulfate-chloride ...

    2020-1-15 · The aqueous solutions used in the copper extraction experiments contained 6 g/l of Cu(II), 5 g/l of Fe(II) and 2 g/l of Fe(III). The solutions were prepared by adding sulfate salts of Cu 2+, Fe 2+, and Fe 3+ in either distilled water or seawater. Sodium chloride was used when necessary to adjust the total chloride concentration to 19.6, 60 and 110 g/l.

  • Solvent Extraction of Copper from Chloride Solutions

    2021-1-27 · 3.1 Effect of equilibrium pH on copper extraction Copper extraction was carried out using aqueous solution containing 0.01643 M copper and 4 M chloride concentration. The copper extraction with 10 % v/v LIX 984N as a function of pH was studied in pH range -0.08 to 2.5. Fig. 2 describes that copper extraction starts at -0.08 pH and quantitative ...

  • Copper Recovery by Solvent Extraction Techniques

    2017-2-2 · A number of factors in combination are used to determine the number of mixer-settler extraction stages required for a specific duty. Fig. No. 3 shows a

  • Extraction of copper(II) from hydrochloric acid solution ...

    2011-4-1 · Extraction of copper(II) anionic complexes from concentrated chloride solutions with pyridine based extractants has been studied by Borowiak-Resterna and Szymanowski (2000). However, the extraction efficiency of hydroxy-oxime reagents significantly decreases as the chloride concentration increases because the concentration of copper cationic ...

  • Extraction Of Copper | Mining, Concentration, Smelting ...

    2022-1-13 · Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace.

  • Extraction of copper from aqueous solutions

    The extraction of copper is carried out using as the extractant vegetable oil at pH 4 and regulation of pH for a period of not more than 4.5 hours the Method allows to increase the copper recovery in concurrent economy and safety of the process. table 1. Extraction of copper from aqueous solutions relates to the field of extraction of ...

  • Removal of Copper Ions from Aqueous Solution Using

    2021-9-8 · Liquid Surfactant Membrane (LSM) as an alternative extraction technique shows many advantages without altering the chemistry of the oil process in terms of efficiency, cost effectiveness and fast demulsification post extraction. Copper (Cu) extraction from aqueous solution using Liquid Membrane (LM) technology is more efficient than the sludge-forming
