Winnowing is a method used to separate lighter components of mixture from the heavier ones by wind or by blowing air. It is used for the separation of husk from grains. Filtration is the method used to separate an insoluble solid from liquid components of a mixture using a filter. It is used for the separation of mud and water from muddy water. Sieving is a method used for separating components of a mixture which are of different sizes. Sieving is used for the separation of stones and sand. Sand will pass through the sieve leaving behind the stone in that. Conversion of liquid into its vapour is called evaporation. It is used for extracting salt from sea water. Threshing is used for the separation of grains and stalks. Condensation is the process of conversion of water vapour into its liquid form. It is reverse of evaporation process. The practice of separating undesirable solid substances and impurities from useful substances from hand is called handpicking. It is used f or the separation of pulses a nd stones.
