Publisher Summary This chapter discusses the process of solvent extraction for purification of metals. Most of the rare metals are appreciably soluble in both aqueous media and organic solvents. The conditions for high solubility in an organic solvent are often fairly specific to an element, compared with the metal ion impurities with which it may be ...

Predispersed Solvent Extraction
Separation Science and Technology, 1985Abstract A novel method for solvent extraction from aqueous solution dispenses with a mixer-settler as the solvent is precomminuted in the form of aphrons which, after extraction, are buoyed to the surface by micrometer-sized bubbles. Extraction from solutions as dilute as a few parts per billion is possible in seconds.

Solvent extraction of ammine complexes
Talanta, 1967The ammine complexes of zinc and of cobalt(II) can be extracted effectively as the dipicrylaminates or tetraphenylborates by using nitrobenzene as the solvent.

Solvent Extraction of Flaxseed
1994Extraction of ground flaxseed with hexanes or a two-phase solvent system consisting of hexanes and a polar solvent mixture was carried out. The polar solvent was alkanol, 95% (v/v) alkanol or 95% (v/v) alkanol containing 10% (w/v) dissolved ammonia. The latter solvent extraction system using methanol, produced a meal with high content of proteins and ...
