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) is the most abundant copper-containing resource in the earth and is
also widely distributed in solid wastes and secondary resources. Biohydrometallurgy …

Chalcopyrite is a prime, plentiful and widely distributed form of copper-bearing mineral.
Compared with the traditional pyrometallurgy process, biohydrometallurgy has …

Jarosite, beudantite and alunite are members of the alunite supergroup. Minerals like those
have been detected in different environments on Earth. These jarosite-type compounds are …

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

In this work, L-cysteine was introduced as an environmentally-efficient flotation reagent in
the selective separation of molybdenite from chalcopyrite. Its flotation performance and …

For mine site management, the release of acid and heavy metal ions from sulfur-containing
waste rock or tailings (principally chalcopyrite and pyrite) under natural deposit conditions is …

In this study, the role of pyrite in sulfuric acid leaching of chalcopyrite (CuFeS 2) was
investigated by leaching experiments, X-ray photoelectron spectroscopy (XPS) and …
