1 Froth Flotation – Fundamental Principles

1 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

process of flotation column

Froth Flotation/Column Flotation of Fine Particles. Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and

Bubble-Distribution Measurement in a Flotation Column: …

ABSTRACTWith improvement in mineral processing, column flotation technology has undergone enormous changes, and various flotation columns have emerged in large numbers. In this study, three types of laboratory-scale flotation columns, including countercurrent, cyclone, and jet flow, were designed, and their bubble sizes were measured by using an image-analysis technique.

Flotation in a novel oscillatory baffled column

 · In this paper, we evaluate the efficacy of the oscillatory baffled column design as a novel flotation device. It is proposed that the more even distribution of turbulence in the system, as characterised by the shear rate or power intensity, allows the particle–bubble contacting rate to be optimised over a much larger volume of the cell than could be achieved in a conventional stirred system.
