Froth Flotation of Iron Ores
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove …

Recent advances in flotation froth image analysis
Machine vision is widely used in the monitoring of froth flotation plants as a means to assist control operators on the plant. While these systems have a mature ability to analyse physical froth features, such as the colour of the froth and bubble size distributions, research has continued to focus on their use in automated control systems, which is not well established yet.
A significant review of froth stability in mineral flotation
Flotation was first performed in 1860 (Arbiter, 2000) and is a technology that utilizes the differences in physicochemical properties of various mineral surfaces to achieve specific separation (Wills and Munn, 2005), as depicted in Fig. 1.This process involves hydrophobic particles adhering to air bubbles being transported to the froth layer, whereas hydrophilic …
Froth Stability Monitoring A Route to Automatic Flotation
The importance of froth stability in respect to flotation performance has long been recognised. Within a flotation cell, the froth phase further concentrates the collected particles by reducing the recovery of entrained gangue mineral particles. This …

Phenomena in the froth phase of flotation — A review
The froth phase is one of the main components of froth flotation as it defines both the quality of the end product and overall efficiency. The performance of the froth depends on a number of sub-processes that interact in very complex ways, and it is a great research challenge to explicitly name the role of each of these sub-processes.

Modelling for froth flotation control: A review
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 ...
