Froth flotation is an essential processing technique for upgrading low-grade ores. Flotation
separation would not be efficient without chemical surfactants (collectors, depressants …

Xanthates are the predominant collectors used in the sulfide mineral processing industry.
Residual xanthates in mineral processing wastewater result in potential water and air …

The process for selective separation of chalcopyrite, a widely used copper mineral, is a
major challenge for the mineral processing industry due to its natural occurrence of various …

Mineral processing utilizes large amounts of water and aims to reduce water consumption
by recirculation and closing the water loops. This results in accumulation of chemical and …

Pyrite, as a disturbing gangue mineral in the beneficiation of valuable sulfide minerals and
coal resources, is usually required to be depressed for floating in flotation practice …

The industrial application of bioleaching of copper ore has been developed for decades. As
the easily soluble copper ore is gradually depleted, the refractory chalcopyrite becomes an …

The selective separation of pyrite (FeS 2) and chalcopyrite (CuFeS 2) in flotation processes
poses significant challenges due to the activation of the pyrite surfaces by copper ions …

Residual xanthates in mineral processing wastewater cause severe water pollution and
potential air pollution in mining areas. In this work, the subsequent degradation behavior of …

Exponential increasing demands for base metals have made meaningful processing of their
quite low-grade (> 1%) resources. Froth flotation is the most important physicochemical …

The effective separation of chalcopyrite, an extensively utilized copper mineral, presents a
considerable hurdle for the mineral processing sector due to its geological tendency to be …
