 — 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 …

Basic Principle of Froth Flotation Process; Mechanism of Froth Flotation Process; Flotation Equipment; Advantages and Disadvantages of Froth Flotation; Method of Froth Floatation. The method of froth floatation can be classified into three steps: 1. True floatation – In this process, minerals are selectively attached to froth.
