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:

Metal extraction from spent lithium-ion batteries (LIBs) at high pulp density by environmentally friendly bioleaching process
TL;DR: In this article, the authors investigated the bio-leaching of a mixture of LiCoO2-based spent lithium-ion batteries at high pulp density (100g/L) using cost-efficient autotrophic bacteria Acidithiobacillus ferrooxidans.
Journal ArticleDOI
Kinetics and roles of solution and surface species of chalcopyrite dissolution at 650 mV
TL;DR: In this paper, the dissolution rate of chalcopyrite was found to be positively correlated with the activities of Fe3+, as a Fe 3 + 1.54 ( ± 0.07 ), and H+ as a H + 0.13 ( ± 1.05 ).
Journal ArticleDOI
New insights into the surface relaxation and oxidation of chalcopyrite exposed to O2 and H2O: A first-principles DFT study
TL;DR: In this paper, the surface anisotropy of chalcopyrite surfaces was investigated under both dry and aqueous atmospheres through a fundamental density functional theory (DFT) study.

Cooperative bioleaching of chalcopyrite and silver-bearing tailing by mixed moderately thermophilic culture: An emphasis on the chalcopyrite dissolution with XPS and electrochemical analysis
Hongbo Zhao,Hongbo Zhao,Jun Wang,Jun Wang,Xiaowen Gan,Xiaowen Gan,Minghao Hu,Minghao Hu,Erxing Zhang,Erxing Zhang,Wenqing Qin,Wenqing Qin,Guanzhou Qiu,Guanzhou Qiu +13 more
TL;DR: In this paper, the interactions between one sample of silver-bearing tailing (223 g/t silver) and chalcopyrite during bioleaching by mixed moderately thermophilic culture were investigated.
Journal ArticleDOI
A critical review of the passivation and semiconductor mechanisms of chalcopyrite leaching
G.M. O'Connor,Jacques Eksteen +1 more
TL;DR: The idea that chalcopyrite leaching is hindered by a passivation layer is challenged in this paper, where it is shown that in alkaline solutions with a complexing agent there is no passivating effect.

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.
