Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

Concentration or Dressing of Ore. The ores are found mixed with earthy impurities like sand, clay, lime stone, etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores.

After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form i.e. the native form of metal. First, we must convert the ore to a suitable form. The metals need to be in an oxide form for the reduction process to be easier. Hence the ores are converted to oxides, so it is ideal for reduction.

To initiate the reduction process, an ignition mixture (usually magneisium and barium peroxide) is used. BaO 2 + Mg → BaO + MgO During the above reaction a large amount of heat is evolved (temperature upto 2400°C, is generated and the reaction enthalpy is – 852 kJ mol ) which facilitates the reduction of Cr 2 O 3 by aluminium power.
