Interfacial Separation of Particles is concerned with the processing and separation of fine solid particles in liquid solutions using interfacial technology.
Interfacial separation has been finding wide application in many industrial fields, such as pigment and filler production, mineral processing, environmental protection, hydrometallurgy, bioengineering, food and beverage industry and chemical industry.
This book describes all interfacial separation techniques and discusses the general and specific fundamentals of the techniques. The book intends to promote theoretical understanding and the more promising developments of interfacial separation technology whilst broadening the reader's background knowledge of industrial suspensions.
* Is clearly written based on strong systematic science fundamentals
* Provides comprehensive coverage on particle technology, mineral processing and water treatment
* Includes practical examples from the different industrial fields
