Inhibition performance and adsorption of polycarboxylic

Mar 15, 2019 In the mineral flotation field, Zhang et al. (2014) showed that polyacrylic acid could selectively inhibit calcite in scheelite flotation, and the flotation separation of scheelite from calcite can be effectively achieved using sodium oleate as the collector. However, little research has been reported on the application of other polycarboxylic

The interaction mechanism of Fe3+ and NH4+ on chalcopyrite

The micro-flotation tests showed that the combined use of Fe 3+ and NH 4 + can not only inhibit arsenopyrite but also activate chalcopyrite. The action of Fe 3+ on the surface of the two minerals leads to a deeper oxidation of the mineral surface, and hydrophilic compounds are produced on the mineral surface to inhibit flotation.

Sep 30, 2018 The flotation behaviors of diatomite and albite using dodecylamine (DDA) as a collector were investigated and compared. The pure mineral flotation results indicate that the flotability difference between albite and diatomite is above 87% at pH 5.5 to 10.5. The recovery of albite improves with increasing DDA dosage at pH 5.5 to 10.5.
