Book Description
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).

Book Description
K.J. Ives Professor of Public Health Engineering University College London The aggregation of small particles in liquids, to form flocs which are large enough to settle, or to be filtered, is a common operation in industrial processes, and water and wastewater treatment. This aggregation, given the general title flliocculation in this book, may be brought about by the addition of chemicals to reduce the stability of the original suspension, by neutralising electrical forces of repulsion, by the addition of chemicals (polymers) to link particles by bridging action, by the addition of chemicals which form particles to increase collision proba bilities, and by the input of energy leading to hydrodynamically induced collisions. The particles undergoing flocculation may range from colloidal in the nanometer size range, through micro scopic (micron) size, up to visible particles in the millimeter size range; that is a total size range of six orders of magnitude. Consequently the colloid chemist and the hydrodynamicist are both concerned with the interactions that take place, and to them the engineer must turn, to obtain the fundamental information ne cessary for the process design and its associated hardware.

Book Description
This book highlights the principles and technologies of flotation machine mainly used in mineral processing in detail. Froth flotation is one of the most important mineral processing techniques. Over 90% of the nonferrous minerals and 50% of the ferrous minerals in the world are treated using flotation: a complicated technique including procedures from chemistry, physics and multi-scale fluid mechanics. The book introduces readers to air-forced and air-induced flotation cells and discusses the various mechanical structures and working principles involved. A number of examples from industrial engineering practice are also discussed throughout the book, helping readers to better understand the technology and relevant equipment. The book is intended for researchers, professionals and graduate students in the fields of mining and mineral processing engineering.

Book Description
The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems has been a major contributing factor to the success of environmental engineering and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

Book Description
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.
