A case of ferrous sulfate addition enhancing chalcopyrite leaching
TLDR
In this article, it was found that several chalcopyrite samples were more effectively leached in ferrous sulfate solution than in ferric sulfate, and the amount of extracted copper increased markedly with increasing ferrous oxide addition and decreasing pH.About:

Journal ArticleDOI
The bioleaching of sulphide minerals with emphasis on copper sulphides — A review
TL;DR: The main focus is on heap bioleaching of whole ores, and the development of models to describe heap and dump processes that can be applied in the design phase as well as to optimise metal extraction.

The geochemistry of acid mine drainage
David W. Blowes,Carol J. Ptacek,John L. Jambor,Christopher G. Weisener,Dogan Paktunc,W.D. Gould,D.B. Johnson +6 more
TL;DR: In this article, the authors developed and applied molecular tools to determine the activity and role of microorganisms in sulfide-mineral-bearing systems and developed tools for assessing the toxicity of mine-waste effluent.
Journal ArticleDOI
A review of the structure, and fundamental mechanisms and kinetics of the leaching of chalcopyrite.
TL;DR: 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.
Journal ArticleDOI
A critical review of the surface chemistry of acidic ferric sulphate dissolution of chalcopyrite with regards to hindered dissolution
TL;DR: In this paper, a conceptual 4-stage model is proposed which explains all the general dissolution behaviour that is widely observed, i.e. of an induction period and a parabolic rate curve that may or may not be followed by linear rate behaviour.

Geochemical and mineralogical aspects of sulfide mine tailings
Matthew B.J. Lindsay,Michael C. Moncur,J.G. Bain,John L. Jambor,Carol J. Ptacek,David W. Blowes +5 more
TL;DR: In this article, the authors investigated the effect of acid acid neutralization on the mobility of sulfide-oxidation products within sulfide mine tailings and found that the extent of acid neutralisation is a principal control on the pore-water pH.
