The characteristic feature of the flotation process is the interaction of gas bubbles with solid particles in a dispersion medium. This monograph reviews the state of the art from the point of view of colloid science, i.e. the heteroparticle interaction. A number of process engineering aspects and physically-based approaches to modelling the flotation process are also taken into account. Special emphasis is on: hydrodynamic interaction of bubble-particle flow; properties, stability and significance of thin liquid films formed as bubbles and particles collide; kinetics of three-phase contact mobility; balance of forces between adhering particles and gas bubbles under static and nonstatic conditions (stability of bubble-particle aggregates).Trends for new applications are discussed and concise descriptions given of new laboratory methods of use to workers in colloids and interfaces. All essential topics are described and derived mathematically in order to enable the reader to calculate the numerical values of interest to him.

Keeping pace with explosive developments in the field, Colloidal Science of Flotation reviews and updates the fundamentals of the bubble-particle collection phenomenon using a self-consistent approach that helps readers understand the hydrodynamic aspects of bubble-particle collection. The authors examine bubble rise velocity, water velocity around air bubbles, the thinning of intervening liquid films, the stability of particle-bubble aggregates, and macroscopic processes in froth. They also survey the applicability of emerging technologies in industrial flotation deinking, wastewater treatment, flotation of plastics, and improvements in minerals and coal flotation.

The present book is the outcome of an Advanced Study Institute meeting, which was held in Kallithea, Chalkidiki, in Northern Greece, from 12-25 May 1991 and attended by 69 delegates from 18 countries. 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; b) chemical technology aspects; c) mineral processing; and d) water and wastewater treatment. Apart from the papers reproduced in this volume, several short oral communications were also presented. Participants also had the opportunity to visit the Hellenic Chemical Products & Fertilizers Co. Ltd. mixed sulphides plant, in Chalkidiki. Conference participants, whose interest and research projects are in this broad field of science and engineering, provided 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 for students, scientists and technologists working in the fields of separation processes and in particular mineral processing and wastewater engineering. All the invited speakers and the participants made this summer school possible, worthwhile and enjoyable. The sponsorship by the NATO Scientific Affairs Division is gratefully ack nowledged. The Editors would like to thank the members of the Organizing Committee, Dr. B.A.

K.J.Ives Professor of Public Health Engineering University College London Industrial application of the use of bubbles to float fine particles in water began before the beginning of this century, in the field of mineral processing. Such bubble flotation was applied very little outside mineral processing, until about 1960 when the dissolved air process, which has already had some success in the pulp and paper industry, was applied to water and wastewater treatment. The subsequent two decades saw not only a growth development for water and wastewater treatment, but also a growing cognisance of the similarities that existed with mineral processing flotation. Therefore the time seemed ripe in 1982 for a joint meeting between experts in these two major fields of flotation to put together the Scientific Basis of Flotation in the form of a NATO Advanced Study Institute. Attended by about 60 specialists, mainly post doctoral, from 17 countries, this Study Institute in residence for two weeks in Christ's College, Cambridge (UK) heard presentations from several international experts, principally the 8 co-authors of this book. The integration of the various scientific disciplines of physics, physical chemistry, colloid science, hydrodynamics and process engineering showed where the common basiS, and occasional important differences, of flotation could be applied to mineral processing, water and wastewater treatment, and indeed some other process industries (for example: pharmaceuticals, and food manufacture).
