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:

Fe(III)/Fe(II) reduction-oxidation mechanism and kinetics studies on pyrite surfaces
TL;DR: In this paper, the effect of the pyrite origin and the Fe(III) and Fe(II) ion concentration on the electron transfer kinetics of the reaction was probed.

Electrochemical simulation of redox potential development in bioleaching of a pyritic chalcopyrite concentrate
TL;DR: The majority of the world's copper reserves are bound in the sulphide mineral chalcopyrite (CuFeS2), but supply of the copper is hindered by the recalcitrance of chal copyrite to bio-leaching as discussed by the authors.

The effect of visible light on the dissolution of natural chalcopyrite (CuFeS2) in sulphuric acid solutions
TL;DR: In this article, the effect of visible light on the anodic dissolution of chalcopyrite in 0.3 M sulphuric acid using a rotating disc technique has been studied.

Effects of different energy sources on cell adhesion and bioleaching of a chalcopyrite concentrate by extremophilic archaeon Acidianus copahuensis
TL;DR: In this paper, the effect of culture growth history on the attachment of Acidianus copahuensis to a chalcopyrite concentrate was investigated in shake flasks at 65°C.
Journal ArticleDOI
Enhanced "contact mechanism" for interaction of extracellular polymeric substances with low-grade copper-bearing sulfide ore in bioleaching by moderately thermophilic Acidithiobacillus caldus.
TL;DR: In order to enhance the "contact mechanism" governing the interaction of extracellular polymeric substances (EPS) with low-grade copper-bearing sulfide ore for the bioleaching of copper, moderately thermophilic Acidithiobacillus caldus was subjected to exogenous intervention with iron and sulfur.

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.
