Copper and molybdenum are important metal resources, efficient treatment and utilization of
copper and molybdenum ores are of great significance to the development of economy and …

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 development of flotation reagents with high selectivity and strong depression ability is of
great significance in the efficient enrichment of copper sulfide ores. In this work, a new …

Separating chalcopyrite, an important copper-containing ore, from pyrite is an important
mineral-processing objective. Herein, we report the synthesis of S-hydroxyethyl-O-isobutyl …

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

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 …

Recently, the copper industry is facing a challenge in dealing with low-grade copper ores
and the flotation performance deteriorates when a copper ore with an elevated pyrite …

During the separation of sulfide minerals, the problem of low selectivity always arises. A
novel thiadiazole derivative (CSC-1) was developed for the flotation of sulfide minerals. The …

The selective depression effect and mechanism of the organic depressant sodium dimethyl
dithiocarbamate (SDD) on pyrite in the flotation system of chalcopyrite and pyrite at low …
