1 Froth Flotation Fundamental Principles

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air

Froth Flotation Metallurgist & Mineral Processing Engineer

Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and control of a flotation process are
