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:

Bioleaching of chalcopyrite by pure and mixed culture
TL;DR: For example, this paper showed that 46.27% of the pH values were lower than 30.37% for the first 75 d of the year, while the remaining 75 d were higher than the previous 75 d.

Heap Leaching: Modelling and Forecasting Using CFD Technology
TL;DR: In this paper, a comprehensive hydrodynamic CFD model is described and applied to chalcopyrite dissolution under heap operating conditions, and validated against a range of experimental leach tests under different thermal conditions.

Fabiana A. Arena,Patrícia H. Suegama,Denise Bevilaqua,Ana Laura Araújo Santos,Cecilio Sadao Fugivara,Assis Vicente Benedetti +5 more
TL;DR: In this paper, an electrochemical study using a carbon paste electrode modified with chalcopyrite (CuFeS 2 ) in solution A of T&K medium with different ferrous ion concentrations, in the absence and presence of the bacterium Acidithiobacillus ferrooxidans, was performed.
Journal ArticleDOI
Adsorption and depression mechanism of an eco-friendly depressant PCA onto chalcopyrite and pyrite for the efficiency flotation separation
TL;DR: In this article, polypropylene carboxylic acid (PCA) was used as an environmentally friendly depressant to efficiently separate pyrite from chalcopyrite, and the separation performance was evaluated by micro-flotation experiments.

Enhanced microbial corrosion of stainless steel by Acidithiobacillus ferrooxidans through the manipulation of substrate oxidation and overexpression of rus
TL;DR: The modification of the culturing conditions and the use of rus‐overexpressing cells led to a more than threefold increase in the corrosion of SS316 stainless steel, such that 15% of the metal coupons was dissolved in just 2 weeks.

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.
