The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using
selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually …

Electrochemical techniques are very useful tools for characterizing the surface properties of
natural minerals involved in electrochemical reactions. This work reviews the recent …

Abstract Copper ions (Cu 2+) are usually added to activate the sulfidized surface of zinc
oxide minerals to enhance xanthate attachment using sulfidization xanthate flotation …

Smithsonite is a typical zinc oxide mineral, and the flotation index is not ideal for the
recovery of smithsonite via sulfidization–xanthate flotation. In this study, Pb 2+ was used as …

In general, malachite is recovered via sulfidization–xanthate flotation, although many
unsatisfactory flotation indexes are frequently obtained as a result of the presence of …

Ethanediamine was used to modify the mineral surface of malachite to improve its
sulfidization and flotation behavior. The activation mechanism was investigated by …

This study systematically investigates the enhanced adsorption of sulfide species onto
cerussite by surface modification with chloride through density functional theory calculations …

Enhancing the sulfidization of copper oxide minerals has been widely studied to improve
flotation recovery. In this study, we investigated azurite surface modification with lead ions …

The interaction between sulfide ion species and malachite surfaces in relation to flotation
was studied in this work using X-ray photoelectron spectroscopy analysis, surface …

The interaction between sulfide-ion species and smithsonite surfaces and its response to
flotation performance were investigated by means of microflotation experiments, surface …
