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

Talc is one of the most problematic hydrophobic gangue minerals that occur in sulfide ores
such as molybdenite and Pt-bearing nickel sulfide ores. Owing to its strong natural …

In this study, a selective depressant sodium alginate (SA) was used to improve the flotation
performance of separating apatite from dolomite. The flotation results show that SA can …

A novel method to improve carboxymethyl cellulose (CMC) performance in talc flotation is
described in this paper. Micro-flotation results showed that using CMC as the depressant …

Polysaccharides are adsorbed on mineral surfaces through interaction with the adsorption
centers on mineral surfaces that are in the form of hydroxylated metallic sites. This …

Tragacanth gum (TG) was explored as a depressant to realize the flotation separation of
molybdenite and talc. The flotation experiments indicated that when using potassium butyl …

To study the role of surface oxides in the adsorption of polysaccharide depressant on
sulfides, the depression behavior of locust bean gum on sphalerite flotation in the presence …

In the flotation separation of chalcopyrite and talc, depressants are usually added to
selectively prevent talc from floating. Commonly used depressants lack selectivity, resulting …

In this study, the depressive effect of xanthan gum (XG) on molybdenite and talc flotation
was studied using potassium butyl xanthate (PBX) as collector, and the mechanism through …

Guar gum is an effective depressant of talc, but it also has some depression effect on sulfide
minerals. To find new selective depressants, the depression effects and mechanisms of …
