Pyrite is a gangue mineral widely associated with valuable minerals. It is problematic to deal
with in differential flotation because it easily reports to flotation concentrates. Pyrite may float …

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

Flotation is the most effective solution, both technologically and economically, when
upgrading iron concentrates. Research regarding iron ore flotation began in 1931 …

In the present study, dithiouracil was employed as the chalcopyrite depressant to selectively
change the properties of chalcopyrite surface and separate molybdenite from chalcopyrite …

Polysaccharides are some of the most widely employed flotation reagents in the mineral
processing industry. Among several, starch is of particular importance for reverse flotation of …

Flocculation and settling performance (kinetic, robustness, upflow velocity, and overall solids
removal) have been significantly improved over the past forty years due to the development …

Due to environmental issues and the restrictions imposed on mineral flotation separation,
the use of biodegradable and environmentally friendly reagents has gained widespread …

In the present work an intense bibliographic search is developed, with updated information
on the microscopic fundamentals that govern the behavior of flotation operations of …

Froth flotation has been a commonly employed technique to enrich natural ores by removing
impurities based on the surface properties of minerals. This process involves the use of …

The separation of arsenopyrite from pyrite has always been a complication due to the lack of
green and high-efficiency flotation reagents. In this study, a macromolecular organic …
