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 …

This article reviews the use of seawater in mining with an emphasis on its use in Chile. The
importance of the use of seawater in mining is highlighted in the introduction, then the main …

Hydrometallurgical process developments for the extraction of copper from chalcopyrite tend
to target complex concentrates, dirty concentrates that would incur penalties if smelted or …

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 …

A conceptual flowsheet is proposed and the main processing steps are evaluated for the
alkaline processing of chalcopyrite where glycine is the complexing agent. Glycine is utilised …

Because chalcopyrite leaching requires high oxidation and existences impurity
encapsulation, a new method for constructing an advanced oxidation system via an …

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

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has
various limitations. In this study, a solvometallurgical process for the extraction of copper …

The seawater is purified or pre-treated to obtain the acidic seawater-based media (ASM),
which has been gradually utilized in copper hydrometallurgical industries, resulting in …

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