Thermodynamic investigations on chalcopyrite
Metallurgical Transactions B, 1975The vapor pressures of sulfur in equilibrium with various compositions within the Cu−Fe−S system were measured by a molecular absorption technique. Measurements were made as functions of temperature for the single phase compositions CuFeS1.62, CuFeS1.70, CuFeS1.80 and CuFeS1.90, for the two-phase fields bornite+chalcopyrite and pyrrhotite+chalcopyrite,

Chalcopyrite Structure Semiconductors
1988The chalcopyrite structure semiconductors composed of elements from columns II, IV, and V of the periodic table represent a natural extension of the III–V zinc-blende compounds. These ternary compounds have very interesting linear and nonlinear optical properties.

Phonons in chalcopyrite compounds
AIP Conference Proceedings, 1999The phonon dispersion curves along the [100] and [001] directions of CuInSe2 and AgGaSe2 have been measured by inelastic neutron scattering. They are analyzed with different rigid-ion models: Born-von Karman and valence force field models. The calculated dispersion curves are in good agreement with experiments.The phonon dispersion curves along the ...

Electrical properties of chalcopyrite
British Journal of Applied Physics, 1958The conductivity σ and thermoelectric power of synthetic and natural specimens of chalcopyrite have been investigated in the temperature range -140 to 300° C. The Hall coefficient R of the natural specimens has also been measured in this region, but in the case of the synthetic specimens is too small to be detected.

Chloride leaching for chalcopyrite
2009Two new process flowsheets have been developed which combine chloride leaching for chalcopyrite with solvent extraction, to selectively transfer copper to a conventional sulfate electrowinning circuit. Both models were designed to address the common chloride hydromet problem of product impurity, and they differ with respect to iron deportment. Chloride

The current focus of research in the UCT Minerals Bioprocessing Research Unit is to develop an understanding of the chalcopyrite bioleaching sub-processes. This thesis forms part of the greater study on bioleaching, investigating the ferric leaching subprocess. The objective of this thesis was two-folds.
