Copper Recovery by Solvent Extraction Techniques
Since then the technique has been applied to the recovery of the rarer metals including columbium, tantalum, and rare earths. In the early 1960s General Mills Chemicals, Inc. developed a solvent designated LIX 63, for the extraction of copper from splutions of pH greater than 4.0.

The effect of diluents on the metal extracted and phase
Ritcey and Lucas [4], while studying the extraction of copper, noticed a decrease in the extraction of the metal with an increase in both the polar nature and the dielectric constant of the diluent employed. As shown in Table 2, sim- ilar conclusions can be drawn for the extraction of aluminium with monononyl phosphoric acid in selected diluents.

Copper extraction - Wikipedia
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. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

The effect of diluents on the extraction of rare earth
The extraction of microquantities of rare earth elements (REE) by methyl-n-diheptylamine solution in mesitylene, p-xylene, toluene, benzene and nitrobenzene has been examined. The parameter measuring the solvation of extractant in aqueous and organic phases has been suggested to describe quantitatively the influence of diluents on the extraction of REE. It was found that in spite of the

Copper amp; Nickel Solvent Extraction
Nickel and copper were co-extracted from ammoniacal ammonium sulfate leach liquors (pH-9.5) with LIX 64N extractant in a laboratory-size mixer-settler continuous circuit. Three extraction stages resulted in gt;99-pct extraction of nickel, substantial copper extraction, and essentially no cobalt extraction from leach liquors.

Effect of diluents on extraction behavior of rare earth
The extraction of rare earth elements with N,N,N,N-tetrabutyl- 3-oxy-glutaramide (TBDGA) in different diluents from hydrochloric acid medium was investigated to evaluate the effect of diluent on the distribution ratio and the stoichiometry of extracted species.
