i)Production of high vacuum: Traces of air can be adsorbed by charcoal from a vessel, evacuated by a vacuum pump to give a very high vacuum.
(ii)Heterogeneous catalysis:The gaseous reactants are adsorbed on the surface of the solid catalysts. As a result, the concentration of the reactants increases on the surface and hence the rate of the reaction increases.
(iii)Froth floatation process: This process is used to remove gangue from sulphide ores. The basic principle involved in this process is adsorption.
In this process, a mixture of water pine oil is taken in tank. The impure powdered sulphide ore is dropped in through hopper and the compressed air is blown in through the agitator is rotator is rotated several times. As a result, froth is formed and the sulphide ores get adsorbed in the froth. The impurities settled down and are let out through an outlet at the bottom. The froth formed is collected in froth collector tank. After sometime, the ore particles in the froth collecting tank start settling gradually, which are then used for further metallurgical operations.

Answer:
. A vessel is first evaluated by vacuum pump and then connected to another vessel containing an adsorbent like coconut activated charcoal cooled by liquid air. At low temperature the charcoal adsorbs remaining traces of air or gases and produces high vacuum.
