Overview

Froth flotation is the largest tonnage separation operation in the world and a key mineral processing technique. While flotation is conceptually simple (it makes use of surface properties to separate valuable minerals from gangue), the multiphase, multiscale sub-processes involved are not fully understood.

This webinar will explore how a fundamental understanding of flotation physics can be exploited to enhance flotation performance. In particular, the webinar will discuss the challenges associated to studying flotation at different scales, from bubble-particle interactions to froth stability in tanks that are hundreds of cubic meters in size.

A range of experimental and modelling techniques to study flotation pulp and froth phase phenomena, from bench to industrial scale, will also be presented.
