LOSCH W, MONHEMIUS AJ, 1976, AES STUDY OF A COPPER-IRON SULFIDE MINERAL, Surface Science, Vol: 60, Pages: 196-210, ISSN: 0039-6028
Synthetic bornite, Cu5FeS4 has been studied by Auger electron spectroscopy. Sputtercleaned bornite shows a sulphur spectrum with three peaks at 138, 147 and 149 eV. These Auger transitions are different from those observed when sulphur is adsorbed on metal surfaces, where the peaks are at 139, 149 and 154 eV. The adsorption of oxygen on the surface of bornite at room temperature results in the formation of a layer of iron oxide and, in addition, the sulphur spectrum loses its fine structure and shows only a single peak at 148 eV. Under the influence of both the ion sputter beam and the electron beam, the surface composition of bornite shows large and rapid changes which are due mainly to movement of mobile Cu+ ions through the lattice, this movement being caused by surface charging effects.

Radino P, Monhemius AJ, 1976, Cobalt Extraction from Hydrochloric Solutions., Metal ABM, Vol: 32, Pages: 603-609
The possibility of cobalt extraction by di(2-ethylhexyl)-phosphoric acid (di2EHPA) was examined. Lithium extraction from aqueous solutions was also investigated. Experiments were carried out to determine the state of aggregation of di2EHPA and its lithium compound in benzene. The water content of benzene solutions of di2EHPA after equilibration with aqueous solutions was determined, and so was the increase in water content with increasing conversion of the acid to its lithium salt by extraction of lithium ions.
