A review of the structure, and fundamental mechanisms and kinetics of the leaching of chalcopyrite.
TLDR
There is general agreement in the literature that chalcopyrite leaching is significantly affected by solution redox potential with an optimum E(h) range suggesting the participation of leach steps that involve both oxidation and reduction.About:

Journal ArticleDOI
A fundamental study of leaching kinetics and mechanisms of molybdenite assisted by mechanical activation
TL;DR: In this article, the effects of grinding ball size, ball to powder mass ratio, milling speed and time, molar ratio of mineral to oxidants, as well as the influence of solution pH, temperature and leaching time were investigated in detail.
Journal ArticleDOI
Differential expression of extracellular thiol groups of moderately thermophilic Sulfobacillus thermosulfidooxidans and extremely thermophilic Acidianus manzaensis grown on S(0) and Fe (2.).
TL;DR: The results evidently demonstrate that the extracellular thiol groups are most probably involved in elemental sulfur activation and oxidation of the acidophilic sulfur-oxidizing microorganisms.

Lisard Torró,Diego Benites,Jean Vallance,Oscar Laurent,Oscar Laurent,Brayam A. Ortiz-Benavente,Cyril Chelle-Michou,Joaquín A. Proenza,Lluis Fontboté +8 more
TL;DR: Trace element compositions of sphalerite and chalcopyrite have been investigated for four arc-hosted Cretaceous VMS deposits (Maria Teresa, Perubar, and Palma in Peru, and Cerro de Maimon in the Dominican Republic) using laser ablation inductively-coupled plasma mass spectrometry as mentioned in this paper.
Journal ArticleDOI
The influence of impurity monovalent cations adsorption on reconstructed chalcopyrite (001)-S surface in leaching process
TL;DR: In this article, the effects of impurity cations released from the gangue are not yet well understood, but the 3d orbital of Fe and 3p orbital of S predominantly contribute to their activities during chalcopyrite oxidation and dissolution processes.

Cupric and Chloride Ions: Leaching of Chalcopyrite Concentrate with Low Chloride Concentration Media
Cynthia M. Torres,Yousef Ghorbani,Pía Hernández,Francisca J. Justel,Matías I. Aravena,O. Herreros +5 more
TL;DR: In this article, the effect of the cupric and chloride ions concentrations on copper dissolution from chalcopyrite concentrate was studied in acidified media, and the results indicated that addition of Cl− to the system improves copper extractions, especially at higher concentrations of Cu2+.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

Photoelectron spectroscopy : principles and applications
TL;DR: In this paper, the three low-index faces of a Face-Centered Cubic (fcc) Crystal Face were modeled as 3D cubic faces, and a table of binding energies was presented.
