Froth Flotation Process Detailed Explanation With

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.60 Centuries of Copper: The Flotation Process,In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.Copper Flotation Elmhurst University,The copper minerals and waste rock are separated at the mill using froth flotation.
