Role of frother on bubble production and behaviour in ...

Nov 01, 2008  1.. IntroductionThe addition of frother is nearly universal in mineral flotation plants. Among the exceptions are operations where high salt levels in the process water can replace the two prime functions of the frother, namely to act in concert with the gas dispersion device to control (reduce) bubble size, and to provide froth-building capacity.

Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

A Review of Flotation Physical Froth Flow Modifiers

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel increases with an increase in the ...
