Book Description
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.

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.

Book Description
The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Book Description
Particles in water play an important role in all kinds of water quality and treatment issues. Since the early beginnings of centralised water production and treatment, the main goal of water purification was primarily the removal of water turbidity in order to produce clear water free from visible particles. The Handbook on Particle Separation Processes provides knowledge and expertise from a selected group of international experts with a wealth of experience in the field of particles and particle separation in water and wastewater treatment. The Handbook on Particle Separation Processes includes an edited selection of presentations and workshops held at the academic summer school Particle Separation in Water and Wastewater Treatment, organised under the supervision of the IWA Specialist Group Particle Separation.

Book Description
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.
