Talc Flotation | Encyclopedia MDPI
Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective …

Effect of clay crystal structure on froth rheology in flotation
The nature of a clay mineral in aqueous solution is related to its crystal structure. Most clay minerals are phyllosilicates which are made up of silicon‑oxygen tetrahedrons (T) and aluminum‑oxygen octahedrons (O) in certain proportions [9].Montmorillonite (T-O-T), kaolinite (T-O) and talc (T-O-T) are common clay minerals present in froth flotation, as shown in Fig. 1.
