उत्तर
Different components of a mixture are separated in order to either separate the un-required components from a mixture or sometimes, to separate more than one useful component from a mixture.
For example, grain purchased from shops can contain several impurities such as pieces of stone, husk, broken grains, etc. Thus, grain is separated from these impurities to make it edible.
Similarly, after preparing tea, we strain it to remove the used tea leaves from tea.
