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 …

As high-grade ore deposits become depleted, there is an increasing demand to process
marginal low-grade ores with complex metallurgical challenges. Orebodies can be rich in …

The flotation separation of chalcopyrite from pyrite has attracted increasing attention due to
the consumption of vast water resources and depressants. This study proposed the …

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 …

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 flotation separation of pyrite and chalcopyrite, and the comprehensive
utilization of AMD play a vital role in the cleaner production of copper sulfide ore. In this …

Various studies have emphasized the importance of surface oxidation of sulfide minerals
with regard to xanthate adsorption and their flotation response. However, the correlation …

Differences in the oxidation rate and extent of model pyrite and arsenopyrite minerals,
augmented by pulp aeration, was investigated using dissolved oxygen demand tests and X …

Effective and low-cost flotation separation of chalcopyrite and pyrite has always been a
challenge in the minerals processing industry. Traditional depressants in a Cu–Fe sulfide …

Moderate oxidation is beneficial to the flotation of sulfide ores, but the exact dissolved
oxygen (DO) concentration suitable for flotation is still unclear. In this work, a self–made …
