CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION …
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. Flotation is a selective process and can

How Froth Flotation Works
How Froth Flotation Works. To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids.

The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
