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:

Effect of temperature-induced phase transitions on bioleaching of chalcopyrite
TL;DR: In this article, the phase transformation of chalcopyrite and the effect of its phase status on bacterial leaching were studied under the protection of high-purity argon.
Journal ArticleDOI
Effect of redox potential on chalcopyrite dissolution imposed by addition of ferrous ions
TL;DR: In this paper, the role of redox potential on chalcopyrite bioleaching by addition of ferrous ions was evaluated and the results showed conclusive evidence that the maintenance of low Redox potential and the addition of Ferrous ions have positively influenced the copper recovery and confirmed the literature data.

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.
