This paper presents a review of the published articles related to froth stability and its
importance in mineral flotation. Froth structure and froth stability are known to play a …

The last few decades have seen major advances in instrumentation and technology, and
simplifications and modifications of new flotation plant designs. This has allowed for …

Research and development into the application of machine vision in froth flotation systems
has continued since its introduction in the late 1980s. Machine vision is able to accurately …

Coal flotation is a complex process involving several phases (particles, oil droplets and air
bubbles). These phases simultaneously interact with each other and with other species such …

It is now generally accepted that froth appearance is a good indicative of the flotation
performance. In this paper, the relationship between the process conditions and the froth …

Froth structure and stability are known to play important roles in determining mineral flotation
recovery and selectivity. However, measuring froth stability quantitatively, both at laboratory …

The rate of flotation and froth stability affect froth flotation performance and selectivity and
strongly depend on various parameters such as the reagent adsorption, particle and bubble …

Air recovery, or the fraction of air entering a cell that overflows the cell lip as unburst
bubbles, is an important measure of froth stability as it affects the flow of bubble surface to …

Reagent usage and type of reagent are important factors in froth flotation. The recovery and
purity of the final product obtained depend on various parameters such as the type and the …

In flotation process monitoring, visual soft sensors provide stable and reliable online
estimations for a concentrate grade, which is difficult to be measured online owing to …
