The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the

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.

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores
