The weathering process of seafloor massive sulphide (SMS) deposits can be considered
analogous to weathering of terrestrial volcanogenic massive sulphides (VMS) deposits …

Chalcopyrite is the most important and abundant raw material for copper extraction in which
hydrometallurgical leaching is more attractive. However, the leaching rate is limited, which is …

Copper concentrates with mineralogy dominated by chalcopyrite have slow leaching
kinetics at atmospheric pressure in sulphate media because of the formation of passivation …

Sulfide copper mineral, typically Chalcopyrite (CuFeS 2), is one of the most common
minerals for producing metallic copper via the pyrometallurgical process. Generally, flotation …

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 …

In this work, bioleaching and dissolution processes of chalcopyrite from three different
regions were investigated and compared mainly by leaching experiments, scanning electron …

The objective of this study is to compare the reaction kinetics of copper leaching from
chalcopyrite in acidic ferric sulfate media with (UAL) and without (non-UAL) ultrasound …

Abstract (Bio) Hydrometallurgy is a common technology in processing copper sulfide
minerals. With the decline in ore grades and depletion of easily mined deposits, some …

Dissolution and oxidation of sulfide minerals play key roles in both acid and metalliferous
rock drainage and supergene enrichment. Surface speciation heterogeneity, critical to …

In this study, the influence of pyrite on the leaching of arsenopyrite in sulfuric acid and iron-
free 9K medium was investigated by leaching experiments and electrochemical analysis …
