• Sieving= This method is used when the mixture contains components of different sizes. A sieve is made by fitting a mesh into a frame. The size of holes in the mesh varies for different mixtures. When a mixture of solids is sieved, those which are larger in size than the holes in the sieve remain on it, while the smaller ones passes through.
