TL;DR: In this article, the rate of the forward reaction depends on the ratio of the total copper to free proton concentration in the aqueous phase and that of the reverse (stripping) reaction on the product of the copper concentration in organic phase and the free protons concentration in aqueouse phase.

TL;DR: The separation methods used in the hydro-metallurgical field are reviewed and compared in this paper, and problems to overcome in the further development of these separation methods are also identified and discussed in this paper.
Abstract: The separation methods which are used in the hydro-metallurgical field are reviewed and compared. Some processes in solvent extraction in use for recovery of crucial metals which are important to the U.S. defense and economy are presented. Various commercial extractants are reviewed and categorized. Other methods such as liquid membranes and ion exchange resins used for dilute metal ions separation are summarized. These methods are compared with solvent extraction. Problems to overcome in the further development of these separation methods are also identified and discussed in this paper.

Journal ArticleDOI
TL;DR: In this paper, the authors considered biphasic systems consisting of an aqueous electrolyte solution containing a metal cation which, according to the nature and composition of the electrolyte, can exist either as a free (hydrated) ion or as neutral, positively or negatively charged complex species.
Abstract: I. EXTRACTING REAGENTS In the present review, dealing with the kinetics of solvent extraction of metal species, we will consider biphasic systems consisting of: 1. An aqueous electrolyte solution containing a metal cation which, according to the nature and composition of the electrolyte, can exist either as a free (hydrated) ion or as neutral, positively or negatively charged complex species 2. An organic phase which is a solution, in a water-immiscible organic diluent, of an organic molecule called extractant; only organic diluent not exhibiting appreciable extraction properties by themselves will be considered; the extractant will instead be a molecule capable of reacting with the aqueous metal species, transferring them into the organic phase; this reactivity is conferred to the extractant by the presence of a functional group which has binding properties with respect to the metal species; the only purpose of the diluent will then be that of dissolving the extractant and possibly to improve its physica...
