What are the common methods of separation of mixtures?

Common methods of separation of mixtures are techniques used to separate different components based on their physical properties like size, weight, solubility, or state.

Some widely used methods include handpicking, where larger impurities are removed by hand, and threshing, which is used to separate grains from stalks. Winnowing helps separate lighter particles like husk from heavier grains using air.

Sieving is used when particles have different sizes, such as separating flour from bran. Sedimentation and decantation are used to separate heavier insoluble solids from liquids, while filtration is used to remove fine insoluble particles.

Evaporation is used to separate dissolved solids from liquids, like obtaining salt from seawater, and condensation is often used along with evaporation to collect the liquid part.

Each method is chosen based on the nature of the mixture and the properties of its components.
