Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning plant, with the barred (denuded) sulfuric acidاحصل على السعر

15/01/2020 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.احصل على السعر
