"Innovations in Flotation Technology" approaches the flotation process from different points of view and covers all related fields, the emphasis being on the chemical engineering aspects which have, in the past, been relatively underappreciated. Flotation constitutes one of the most significant operations in mineral beneficiation. The process is also applied in water and wastewater treatment, which is very significant in the modern world and the environmental strains that it is under. The recycling of materials and by-products represents a promising area for the application of flotation technology. Work is continuously being carried out on the development of new flotation techniques which offer savings in terms of operating costs and energy, and the book presents some of the more promising of these: new flotation columns and dissolved air and electrolytic flotation. Modern flotation has permitted the mining of low grade and complex ores, overcoming the associated problems such as the existence of fine particles.

Mineral processing technologies have been used for decades to protect the environment and many examples of such applications are given here. The book covers four major subject areas: fundamentals; environmental pollution and its prevention; separation processes; and innovative techniques. The text should be on interest to scientists, engineers and technologists conducting both applied and basic research into the different environmental aspects of mineral processing.

Mineral processing technologies have been used for decades to protect the environment and many examples of such applications are given here. The book covers four major subject areas: fundamentals; environmental pollution and its prevention; separation processes; and innovative techniques. Audience: Scientists, engineers and technologists conducting both applied and basic research into the different environmental aspects of mineral processing.

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.
