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 …

Exponential increasing demands for base metals have made meaningful processing of their
quite low-grade (> 1%) resources. Froth flotation is the most important physicochemical …

Molybdenite is usually associated with chalcopyrite and other sulfide minerals, which
troubles the efficient utilization of Mo resources. Flotation using various surfactants is a key …

In this paper, the effect of Tannic acid (TA), a green, biodegradable plant polyphenol, as a
talc depressant on the separation behavior of talc and chalcopyrite was investigated. The …

Chalcopyrite and talc exhibit strong natural hydrophobicity, making it challenging for
conventional inhibitors to effectively separate the two through flotation. This paper proposes …

The concentrate grade in chalcopyrite flotation is often compromised by the associated
inherently floatable gangue such as graphite. In this study, eco-friendly xanthan gum (XG) …

A key strategy for achieving the selective separation of talc and chalcopyrite is the
development of chemical depressants with high solubility and strong selectivity. Tannic acid …

This study describes the first, use of eco-friendly welan gum as a new depressant in galena-
pyrite flotation separation. The depression mechanism were examined using micro-flotation …

Depressants are essential additives in the flotation separation of scheelite-calcite minerals.
However, traditional inorganic depressants such as sodium silicate have the disadvantages …

Flotation is a main mineral concentration technology, which is why the design of flotation
circuits has been extensively studied in the literature. However, studies on flotation circuit …
