FLOTATION

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle-bubble aggregates that are formed have a density less than the suspension itself ...

Flotation Process - an overview ScienceDirect Topics

The feature making emulsion flotation different from conventional flotation is the presence of a collector in the form of oil droplets, which must collide with mineral particles in order to enhance the probability of particle- to-bubble attachment. The process is based on selective wetting: the droplets of oil can adhere only to particles that ...

Froth Flotation - Metallurgist Mineral Processing

2016-12-19  Froth Flotation 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

Modelling for froth flotation control: A review ...

2021-3-1  1. Introduction. Froth flotation is the largest tonnage separation in mineral processing by which valuable mineral is separated from waste rock. Advances in control and optimisation of the froth flotation process are of great relevance since even very small increases in recovery lead to large economic benefits (Ferreira and Loveday, 2000, Maldonado et al., 2007).
