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 dextrin on flotation separation and surface properties of chalcopyrite and arsenopyrite
TL;DR: The combined effect of these two aspects makes the arsenopyrite treated with dextrin lose its hydrophobicity and enables the separation of chalcopyrite and arsenopyrsite.

Cu 2+ -catalyzed mechanism in oxygen-pressure acid leaching of artificial sphalerite
TL;DR: In this article, the catalytic mechanism of Cu2+ during the oxygen pressure leaching process of artificial sphalerite was studied in the potential autoclave and the potential change of the system at different temperatures and the SEM-EDS difference of the leaching residues was found.

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.
