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 …

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 …

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 …

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 …

This study investigated the effects of H 2 O 2 treatment on xanthate interaction and flotation
separation of chalcopyrite and pyrite by making use of a series of laboratory flotation …

Metal sulfides are usually semiconductor and cause electrochemical reactions. This
phenomenon plays an important role in sulfide flotation. Pyrite as the most abundant sulfide …

The selective separation of molybdenite from chalcopyrite is difficult because of their similar
floatability in the presence of a collector. In this study, rhodanine-3-acetic acid (3-Rd) was …

Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of
pyrite is affected by many factors, causing it to easily enter the concentrate and consequently …

Depressants are critical reagents for the selective separation of minerals in froth flotation.
They serve a vital role in preferentially making the gangue minerals hydrophilic and prevent …

Pyrite depression in copper ore flotation often requires large doses of inorganic depressants
that lead to high toxicity, high costs, and low selectivity. Thus, this study offers a novel pyrite …
