This paper indicates the various ways in which the chemistry of the platinum group metals
(PGM) can be manipulated to achieve separations using solvent extraction techniques and …

Three hydrometallurgical processes for industrial wastes treatment are presented. The main
separation techniques are: solvent extraction, leaching-precipitation, electro-oxidation, and …

Three different kinds of adsorption gels, viz., cross-linked lignophenol, cross-linked
lignocatechol, and cross-linked lignopyrogallol, were prepared by the chemical modification …

Dibutyl carbitol (DBC) and methyl isobutyl ketone (MIBK) are commercially available for the
extraction of Au (III) from acidic chloride media through ion solvation. These extractants …

An improved process was developed to produce gold with purity> 99.9998%(> 5 N) from
gold scraps using dibutyl carbitol (DBC) as an extractant. The extraction of gold into DBC …

Recently, a commercially available ethereal compound, cyclopentyl methyl ether (CPME)
was found to act as an extractant for Au (III) in acidic chloride media. In this study, the …

Iron is the most abundant element by mass in the Earth. Despite being an inexpensive
material used in a wide range of applications, its role as reducing agent for the synthesis of …

Microporous hollow fibers have been used in the extraction of gold from aqueous solutions
into an organic extractant and in the stripping of gold from the organic extractant into an …

Ethereal compounds, such as the commercially available extractant dibutyl carbitol (DBC),
can extract Au (III) from acidic chloride media by ion solvation. Herein, various aromatic …

The kinetics of forward extraction [AuCl4]− from aqua regia medium by diethylene glycol
dibutyl ether (DBC) have been investigated by the Lewis cell (LC) technique. At first gold …
