Most investigators regard CuFeS 2 as having the formal oxidation states of Cu+ Fe 3+(S 2−)
2. However, the spectroscopic characterisation of chalcopyrite is clearly influenced by the …

Chalcopyrite (CuFeS 2) makes up a large and increasing fraction of the world's future
copper resources, but is highly refractory to leaching with common lixiviants. Novel lixiviants …

Water is needed at mine sites for dust suppression, mineral processing, coal washing, and
hydrometallurgical extraction. For these applications, water is mined from surface water …

Sphalerite is an important host mineral for a wide range of minor and trace elements. We
have used laser-ablation inductively coupled mass spectroscopy (LA-ICPMS) techniques to …

We measured the Fe, Cu, and Zn isotopic compositions of the fluids generated during
leaching experiments with pyrite-, chalcopyrite-, and sphalerite-rich rocks and with a …

Bio-hydrometallurgical applications have been receiving more attention globally for
processing of several metal bearing wastes. Developments in bioleaching enable this …

This review outlines classic and current research, scientific documents and research
achievements in bioleaching, particularly in respect of the bioleaching of chalcopyrite and …

Mineralogical, geochemical and microbial characterization of tailings solids from the Greens
Creek Mine, Juneau, Alaska, was performed to evaluate mechanisms controlling aqueous …

Chalcopyrite ores are usually processed by means of hydrometallurgical or
pyrometallurgical processes, but due to environmental aspects and the possibility of …

Extensive pyrite-bearing, auriferous cobble and boulder conglomerates are present in the
basal 30 m of the Mississagi Formation in Pardo and Clement Townships, Ontario, Canada …
