During the selective extraction of Pd II by LIX 63 from 6 M HCl solutions containing platinum group metals an oxidation reduction reaction occurs between the LIX 63 and Ir IV Since the reduced Ir III cannot be extracted by solvating and amine extractants the oxidation reduction reaction has a significant effect on the separation of Pt IV Ir IV and
The bulk sulphide precipitate obtained after addition of Na 2 S to the Fe and Mn free leach liquor of manganese nodule was leached with H 2 SO 4 and the leach liquor contained 13 kg/m 3 copper kg/m 3 nickel kg/m 3 cobalt kg/m 3 zinc and kg/m 3 Na 2 SO of copper from this leach liquor was carried out with the extractants LIX
QN LIX 54 LIX 973 LIX 984 and LIX 34 are used for the extraction sep aration and recover y of copper nickel and zinc from sulphate solutions Reddy and Priya 2005
In recent years the demand for copper and nickel has risen world wide due to their use in printed circuit boards batteries application in marine alloys due to excellent resistance to corrosion by seawater and a wide range applications in day to day life Doebrich 2009 Increasing demand for these metals is leading to rapid depletion of high grade
Firstly we measured the distribution ratios of ammonia using different concentrations of ammonium nitrate solution mol/L at different equilibrium pH values [11 12] The log D NH 3 value at a fixed ammonium nitrate concentration monotonically increased from −3 to − with pH eq from 8 to 10 and then tended to be constant At a fixed pH eq
El efecto del pH y la concentración total de cloruro en la extracción de cloruro sugiere que el LIX 860N IC y en menor grado el LIX 84 IC extraen pequeñas cantidades del catión monovalente
LIX 54 was introduced as a commercial reagent for the recovery of copper from ammoniacal solutions 29 The 2 1 complex in the extraction process shown in eqn 6 is assumed to have a planar structure analogous to that of the acetylacetonate complex shown in Fig 9 30 The aqueous raffinate contains a mixture of ammonium ions and ammonia which
A novel synergistic solvent extraction SSX system consisting of LIX 54 and Cyanex 923 in ShellSol D70 to recover lithium and separate it from sodium in chloride solutions has been developed With the SSX system over 97% of lithium was extracted at pH 11 from a synthetic solution with almost no extraction of sodium in a single contact resulting in a
Acidic carriers like LIX 54 100 need a pH above their pKa to dissociate and form the chelate with interest species The LIX 54 100 pKa value was not determined but it would probably lie close to that of the benzoylacetone [55] However acidic carriers trend to lixiviate from the membrane if in contact with a strong alkaline media [49
The best degree of lithium extraction was obtained with [LIX 54] to [TRPO] ratio of 1 1 At equilibrium pH of [LIX 54] [TRPO] ratio of 5 5 the synergistic extraction coefficient of the synergistic system reaches 4147 which is much higher than the coefficient under other equilibrium pH value It can be seen that for the LIX 54/TRPO
