CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION
2020-5-6 A. Vidyadhar and R. Singh INTRODUCTION Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide selective levitation of the solid particles. It is most extensively used process for the separation of chemically similar minerals, and to concentrate ores for economical smelting.
