Separate three Components from Iron, Sand and Common Salt
In this process, a sieve is used for sieving grains. A sieve has small holes which allow pebbles to pass through it. The grains are retained in the sieve and are thus separated. They depend upon the size of particles to be separated. 4. Magnetic Separation. Using a magnet, iron filings can be separated from a mixture of iron and sand.
