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:

The role of cupric ions in the oxidative dissolution process of marmatite: A dependence on Cu2+ concentration.
Xiaoyu Meng,Hongbo Zhao,Hongbo Zhao,Hongbo Zhao,Menglin Sun,Yisheng Zhang,Yanjun Zhang,Xin Lv,Hyunjung Kim,Mikhail Vainshtein,Shuai Wang,Guanzhou Qiu,Guanzhou Qiu +12 more
TL;DR: Electrochemical measurement and X-ray photoelectron spectroscopy analysis indicated that Cu2+ was first adsorbed on the marmatite surface and then produced Cu-S surface species, thus catalyzing the oxidative dissolution process.

Leaching of chalcopyrite with hydrogen peroxide in hydrochloric acid solution
TL;DR: In this paper, the effects of the leaching variables on metal extraction, such as stirring speed, solid-to-liquid ratio, temperature and HCl and H2O2 concentrations, were studied.
Journal ArticleDOI
Electrochemical dissolution of fresh and passivated chalcopyrite electrodes. Effect of pyrite on the reduction of Fe3+ ions and transport processes within the passive film
TL;DR: The effect of pyrite on the electrochemical dissolution of fresh and passivated chalcopyrite (CuFeS 2 ) electrodes has been studied in this paper, where current density values for the dissolution of CuS 2 were calculated from EIS measurements.
Journal ArticleDOI
Leaching of chalcopyrite ore agglomerated with high chloride concentration and high curing periods
TL;DR: In this article, the effect of the addition of chloride ion in the agglomeration of chalcopyrite ore and the curing time on the overall leaching process was investigated.

Stepwise bioleaching of Cu-Zn mixed ores with comprehensive utilization of silver-bearing solid waste through a new technique process
Hongbo Zhao,Hongbo Zhao,Xiaowen Gan,Xiaowen Gan,Jun Wang,Jun Wang,Lang Tao,Lang Tao,Wenqing Qin,Wenqing Qin,Guanzhou Qiu,Guanzhou Qiu +11 more
TL;DR: In this article, a new technique process for processing Cu-Zn mixed ores containing chalcopyrite and marmatite was proposed to avoid the complex CuZn flotation and extraction separation processes, as well as for the comprehensive utilization of abandoned silver-containing zinc leaching residue.

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.
