Flotation Talc Patent
Minerals | Free FullText | Talc Flotation—An Overview | HTML
Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast appliions 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 separation challenging.

Flotation of chalcopyrite, pentlandite, pyrrhotite ores ...
Nov 01, 1991 · Talc is well known to be natu rally hydrophobic and it is readily floated with only a frother. The talc content has a much greater influence on the flotation results than would be expected from its content in the ore. This is apparently related to the effect that the small amount of talc has on the properties of the froth.
