Principles of Froth Flotation | SpringerLink
For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision ...

Froth flotation of fluorite: A review
So far, significant endeavors have been done to enhance the beneficiation of fluorite from relatively low-grade ores. It has been well appreciated that the froth flotation is of the most importance. However, to the best of the authors' knowledge, it lacks a thorough and critical review on the recent developments in fluorite flotation.
Froth Flotation: Factors affecting, Advantages, Disadvantage
However, froth flotation separates minerals using proper flotation reagents. The minerals that are separated change as the reagents change. In other words, the type of minerals does not affect froth flotation. The froth flotation method is one of the most extensively used processes, and it is prominent in many mineral processing technologies.
