Book 1992d a well-informed discussion of the problems encountered, as well as possible directions of future technological developments. It is hoped that this book is not only a good record of the presentations made (formal and informal), analyzing the state-of-the-art in flotation, but will also be helpful f

Liberation by Size Reduction. Consequences and Improvements on Flotation Kineticse distribution of a given iso-size fraction. Considering this previous general model of liberation by size reduction as a good support, flotation kinetics is reviewed in order to provide evidence for the kinetic rate constants (seen as non-wettability parameters) as dependent on the grade distributi

The Institute brought together scientists, engineers and technologists currently involved in basic and applied research on the different aspects of flotation. The Institute covered subjects in four major areas of flotation: a) fundamentals

The Study of Thin Aqueous Films as Models for Froths and Flotationying the fundamental behaviour of these mineral processing operations is discussed. The characteristic properties of the aqueous film is described and the experimental techniques developed to measure film thickness, stability and intermolecular interactions are reviewed.

Mineral Surface Complexation in Flotationomplexation and their meaning in flotation are presented and discussed and used to interpret surface charge, as well as surface reactions with collectors, activators and depressants. Surface speciation and flotation principles are correlated for a sulphide (e.g. galena) and oxide mineral (e.g. quartz) system.
