Colloidal Science of Flotation

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.

This new book is recommended to our many readers interested in colloid science, especially the fundamentals of separation and concentration of colloidal particles. The book begins with a very useful three-tier table of contents, containing eight parts, each consisting of one or more chapters organized into a series of subcategories. The book is well written, illustrated, and organized. Symbols appearing in the equations are defined at the end of each chapter. There are about 800 references and thorough subject index.
