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 …

The need to process low-grade and/or complex chalcopyrite-containing ores that cannot be
concentrated is the main driver for the development of hydrometallurgical processes. The …

The influence of potential on the species and surface films formed during electrodissolution
of chalcopyrite were investigated in 0.5 M sulfuric acid solution at 25° C. Cyclic voltammetry …

To investigate the essential difference in the water adsorption on the hydrophobic galena
(PbS) and hydrophilic pyrite (FeS2) surfaces, a single, mono-, and multilayer water …

In order to unravel the oxidation mechanism (s) of chalcopyrite (CuFeS 2) surfaces, the
surface anisotropy of CuFeS 2 was investigated under both dry and aqueous atmospheres …

Abstracts The interaction of collector with the mineral surface plays a very important role in
the froth flotation of sphalerite. The adsorptions occurred at the interface between the …

The recovery of copper from secondary waste resources (eg electronic wastes, slag, fly-ash,
sludge and spent catalysts) via oxidative and reductive bioleaching becomes a running …

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in
this method, copper sulfide mineral particles are concentrated in froth, and associated …

The effects of H 2 O 2 on the flotation separation of chalcopyrite and pyrite in seawater were
investigated. Pyrite was more significantly oxidized by 0.05 vol% H 2 O 2 in seawater at pH …

The oxidation of pyrite has attracted significant attention due to its predominant contribution
to the serious environmental issue of acid mine drainage (AMD). However, relatively few …
