What are the different methods used to separate a solid-solid mixture? Explain any two.
What are the different methods used to separate a solid-solid mixture? Explain any two.
Separation of Mixture of two Solids:
1. Mechanical picking or handpicking: In this method, components are separated on the basis of physical characteristics like size and shape.
Example- Removing stones from grains. This technique in which a mixture can be separated by picking them out by hand is called Handpicking. This method can be used to separate slightly larger pieces of dirt, stones and husk from the grains because the quantity of such impurities is usually not very large.
2. Sieving: Sieving is a simple technique for separating particles of different sizes. A sieve such as one used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings.
