Froth Flotation Process - Detailed Explanation With ...

Apr 06, 2020  Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.
