Column flotation of talc

Abstract. Flotation of low grade talc was carried out in a laboratory flotation column with fine air bubbles. Recovery of talc was approximately 83% with a mean residence of 73 s and a whiteness of 84, which was significantly higher than that of a conventional agitation-type flotation cell. A mathematical model was developed to …
