Improved flotation separation of fine particles using hydrophobic

In this work, we demonstrated selective separation of clay particles from soil by flotation separation assisted by hydrophobic silica nanoparticles (HPOS NPs) [19], [20], [21]. Simple dry-mixing of soil with HPOS NPs can increase hydrophobicity of clay particles by adhesion of the HPOS NPs on the clay surfaces via van der Waals interaction [22 ...

Advances in depressants used for pyrite flotation separation from …

Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of pyrite is affected by many factors, causing it to easily enter the concentrate and consequently reduce the quality of concentrate. Highly efficient pyrite depressants can be selectively adsorbed on the surface of pyrite to improve its hydrophilicity, thereby …
