Extraction Equilibrium of Copper from Ammoniacal Media with LIX 54 M. Rosinda, C. Ismael, M. Lurdes, F. Gameiro, Jorge M. R. Carvalho Separation Science and Technology, January 2004, Taylor Francis
· Extraction of copper from ammoniacal solutions with LIX 84 and LIX 54 used alone and their mixture was studied, and a chemical model was proposed and verified. The equilibrium extraction constant was correlated with the ionic strength. The effect is weak for the strong extractant LIX 84 and its mixture but very strong for the weak extractant LIX 54.

LIX®54100 LIX 54100 solvent extraction reagent is a water insoluble reagent, which forms hydrocarbon soluble complexes with various metal cations in a manner similar to that shown below for copper: 2RH(org) + Cu +2 (aq) R2Cu(org) + 2H + (aq) TYPICAL USES LIX 54100 was designed and is most commonly used for the extraction of copper from aqueous
Nickel extraction from ammoniacal media, containing initially g/l of nickel, by LIX 54 in an aliphatic diluent, Iberfluid, has been studied as a function of aqueous pH, equilibration time
The extraction of Cu(II) by LIX 54100 (ßdiketone) in Iberfluid (kerosene type diluent) from ammoniacal/ammonium sulphate solutions has been investigated.
[27] and LIX 54–100 which was specifically developed for the recovery of copper from ammoniacal leaching solutions [2,9] are being used in the industry from the recovery of copper from it leached resources [15]. Recently, Mextral 84H and Mextral 54–100 were synergistically used for the solvent extraction of zinc from
Abstract: The extraction of Cu(II) by LIX 54100 (ßdiketone) in Iberfluid (kerosene type diluent) from ammoniacal/ammonium sulphate solutions has been investigated. The analysis of metal distribution data suggested the formation of CuR 2 species in the organic phase with formation constant log K ext = The results obtained on Cu(II) distribution have been implemented in a solid
Mentioning: 8 The effect of ammonium sulphate and ammonia on the liquid–liquid extraction of zinc using LIX 54 Alguacil, M Alonso
Extraction of copper from ammoniacal solutions with LIX 84 and LIX 54 used alone and their mixture was studied, and a chemical model was proposed and verified. The equilibrium extraction constant was correlated with the ionic strength. The effect is weak for the strong extractant LIX 84 and its mixture but very strong for the weak extractant LIX 54. LIX 54 acts as a modifier of LIX 84 by
The extraction has to take place at a very unfavourable phase ratio. FIG. 3 relates to a mixture of reagents according to the invention, containing 35 percent by volume "weak" reagent (LIX 54), 10 percent by weight "strong" reagent (LIX 65N), and 55 percent by volume kerosene.
LIX® solvent extractants are recognized throughout the copper industry as the go to reagent for copper recovery. BASF''s broad range includes aldoxime and ketoxime extractants and incorporates blends formulated to specific customer needs / operational challenges.
· The extraction of copper from ammoniacal aqueous solutions with LIX 54 was studied by using NDSX with hollow fibres as contactors. Some equilibrium experiments for the system CuSO 4 /(NH 4) 2 SO 4 /NH 3 /LIX 54 were carried out.
