Recovery of copper by LIX 984N-C from electroplating rinse bath solution

Extraction of copper from bacterial leach liquor of a low grade chalcopyrite test heap using LIX 984N-C

“…From the reported literatures (Kul and Cetinkaya, 2009b;Lazarova and Lazarova, 2005), LIX 984N-C was notably found as a very selective chelating extractant towards the extraction of copper metal ion despite of the presence of other impurities in the aqueous solution, while separating the copper ion from the leach solution bearing other metals such as Zn, Pd and Ni. Nevertheless, LIX 984N-C is considered as a strong extractant towards the extraction of copper because of its very good physical performance property.…”

“…A considerable amount of work have been devoted towards the investigation on solvent extraction of copper from acid or ammoniacal medium using LIX series extractants Lazarova, 2005, 2007;Panigrahi et al, 2009;Parija and Sarma, 2000). Off these LIX reagents, LIX 984N-C is found to be an efficient and effective extractant owing to its exclusive applications in extraction of several metals (Cu, Ni, Fe and Zn) by solvent extraction processes (Kul and Cetinkaya, 2009a, 2009b, 2010. In addition, the selectivity of the LIX 984N-C towards any of the above metals was again governed by the change of suitable pH range of the aqueous solutions (Kul and Cetinkaya, 2009b).…”

Effect of the Structure of Alkyl Salicylaldoxime on Extraction of Copper(II)

“…At present, AS are produced by bio-extraction and artificial synthesis, with the artificial synthesis route being the dominant technique for the production of AS [10,11]. It was reported that many types of AS with different R groups (e.g., nonyl, decyl, and dodecyl) have been synthesized in the laboratory [12][13][14][15][16]. Some researchers investigated the extraction ability of AS with more than 12 carbon atoms in the R group for Cu(II).…”

Investigation of Copper Extraction from Aqueous Sulfate Solution in a Rotating Disc Contactor

“…11 Literature review indicates that hydroxyoximes are now used widely as extractants for copper SX in hydrometallurgy marketed as LIX (Cognis), Acorga (ICI) or SME (Shell) reagents. [2][3][4][5][11][12][13][14][15] In recent years, D 2 EHPA and various sulfur containing reagents such as CYANEX group have received considerable attention both for their ability to extract soft transition metal ions. 8,12,16 Over the years different types of solvent extraction contactors have been developed for use in the minerals processing industry.…”
