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:

Chalcopyrite dissolution: Scanning photoelectron microscopy examination of the evolution of sulfur species with and without added iron or pyrite
TL;DR: In this article, a synchrotron scanning photoelectron microscopy (SPEM) was employed to examine freshly fractured and partially dissolved chalcopyrite surfaces (pH 1.0 HClO 4 solution, redox potential 650 mV relative to a standard hydrogen electrode, 75 mV).
Journal ArticleDOI
New insights into the influence of redox potential on chalcopyrite leaching behaviour
TL;DR: In this paper, the effect of solution redox potential on leaching of a pure and a pyritic chalcopyrite concentrate was investigated using concentrates with fresh and aged surfaces.

Bioleaching of chalcopyrite by Acidianus manzaensis under different constant pH
Hong-chang Liu,Jin-lan Xia,Zhen-yuan Nie,Chen-yan Ma,Lei Zheng,Cai-hao Hong,Y. B. Zhao,Wen Wen +7 more
TL;DR: In this paper, the bio-leaching of pure chalcopyrite by thermophilic Archaea strain Acidianus manzaensis YN-25 under different constant pH was analyzed by synchrotron radiation based X-ray diffraction (SR-XRD) and S K-edge Xray absorption near edge structure spectroscopy.

A brief overview on the dissolution mechanisms of sulfide minerals in acidic sulfate environments at low temperatures: Emphasis on electrochemical cyclic voltammetry analysis
Yisheng Zhang,Yisheng Zhang,Hongbo Zhao,Hongbo Zhao,Lu Qian,Lu Qian,Menglin Sun,Menglin Sun,Xin Lv,Xin Lv,Luyuan Zhang,Luyuan Zhang,Jochen Petersen,Guanzhou Qiu,Guanzhou Qiu +14 more
TL;DR: In this paper, the authors summarized the research into the dissolution mechanisms of several sulfide minerals, predominantly under bioleaching conditions, and the effects on the solid phase, including decomposition products and precipitates formed during the degradation processes, are discussed.

Comparative study of S, Fe and Cu speciation transformation during chalcopyrite bioleaching by mixed mesophiles and mixed thermophiles
Hong-chang Liu,Hong-chang Liu,Jin-lan Xia,Zhen-yuan Nie,Li-zhu Liu,Lei Wang,Chen-yan Ma,Lei Zheng,Y. B. Zhao,Wen Wen +9 more
TL;DR: In this article, the results showed that the chalcopyrite dissolution could be significantly promoted by these mixed cultures, and the promotion effects were enhanced with the increase of bioleaching temperature.

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.
