Impure leach solutions containing relatively low concentrations of copper are processed to high copper concentration, …

SX-EW's application in the nickel industry has also promoted its use with cobalt, as the two base metals often occur together. Nickel is a major source of cobalt, but the close placement of nickel and cobalt on the …

The process of cobalt mining involves many steps, including locating suitable deposits and extracting the ore before refining it into a usable form. Cobalt is only extracted alone in …

A combination of hydrometallurgical processes of high-pressure oxidative leaching (HPOL), solvent extraction (SX), and electrowinning (EW) were utilized to recover copper from mine tailings which contain about 0.3% Cu content. The HPOL process yielded a high copper leaching rate of 94.4% when water was used as a leaching medium.

Acquired in 2009. Boss Mining, a copper cathode & cobalt concentrate producer, is one of the Group's core assets. Its operations include open cast mines, crushing, beneficiation, concentrator plants and an electro-winning facility. Facility Description. Open cast mining with heap leach, agitation leach followed by solvent extraction (SX) and ...

A series of tests were made to define the kinetics of: (1) cobalt (II) extraction with XI-51 solvent, (2) NH3 removal from the loaded solvent by H2O- (NH4)2SO4 washing, and (3) the stripping of cobalt from the loaded solvent. These tests were conducted at 20° C in a 180-ml mixer compartment of a mixer-settler stage.
