Principles and technologies of flotation machines / Основы и технология флотационного оборудования

The history of mineral processing over the recent one hundred years has shown that the froth flotation is a predominant technology of mineral beneficiation, and nowadays it is widely used for materials separation, valuables recovery and wastes treatment in the industries of mining, petroleum, chemical engineering, etc. Flotation equipment plays vital roles in the practices of flotation processing. The development of flotation equipment made it possible for more and more traditional and nontraditional ores and materials to be treated by flotation process with high efficiency.
Many books on flotation principles and flotation reagents have been published in the past century, however very few of them emphasizes on flotation equipment and the principles behind. The innovation on flotation machines should be brought to the forefront for the further improvement of flotation technology. The author of this book started the investigation of flotation equipment since the 1980s. This book has summarized the research findings achieved by the author, his research group as well as researchers around the world in the past decades. It starts with the fundamental principles of the physic phenomena such as hydrodynamics of slurry, aeration mechanism, bubble-particle interaction and so on helping readers to understand how a flotation machine works. The principles and approaches of flotation equipment design are then described and discussed in details. An emphasis is put on the scale-up design methods since it has been a trend to design more and more massive flotation machines. The critical structures, key components, typical applications and histories of the equipment from the major suppliers are introduced to provide readers with a whole picture.

This book is suitable for teachers, researchers, R&D engineers, graduate students and professionals in the area of mineral processing and extractive metallurgy who wish to study flotation process knowledge and explore innovative technologies. <...>
