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:

Electrochemical studies on dissolution and passivation behavior of low temperature bioleaching of chalcopyrite by Acidithiobacillus ferrivorans YL15
Weimin Zeng,Weimin Zeng,Weimin Zeng,Yu-ping Peng,Tangjian Peng,Mei-hua Nan,Miao Chen,Guanzhou Qiu,Guanzhou Qiu,Shen Li,Shen Li +10 more
TL;DR: In this article, the electrochemical analysis techniques such as cyclic voltammetry (CV), potentiodynamic polarization curve and electrochemical impedance spectroscopy (EIS) combined with surface detection methods such as scanning electron microscopy (SEM) were applied to study chalcopyrite during bio-leaching at 6°C.

Biological and chemical control in copper bioleaching processes: When inoculation would be of any benefit?
TL;DR: In this paper, a conceptual mathematical model is presented to define when a bio-leaching process is controlled by biological, chemical, or transport phenomena, based on the kinetic analysis of the electrochemical aspects of the microbiological and chemical sub-processes involved in bioleaching.

Kinetics of pyrite, pyrrhotite, and chalcopyrite dissolution by Acidithiobacillus ferrooxidans
TL;DR: Pyrite, pyrrhotite, and chalcopyrite dissolution by A. ferrooxidans was found to be a chemically controlled process and the acid-insoluble trait of pyrite and acid-soluble traits of the other 2 minerals affected the pH changes in the leaching solutions.

Improved understanding of chalcopyrite flotation in seawater using sodium hexametaphosphate
Wanqing Li,Yubiao Li +1 more
TL;DR: In this article, the authors investigated the application of SHMP in chalcopyrite (CuFeS2) flotation in seawater, as well as in the presence of Mg2+ or Ca2+ (two divalent ions displayed the most negative roles on mineral flotation).

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.
