Answer:

Sieving

Explanation:

Sieving is a separation technique based on the difference in particle size. The sieve is responsible for retaining the larger particles.  

Most of the things that we come across in our day-to-day life exist as a mixture of two or more pure substances.  We need to separate these pure substances from the mixture in order to use them individually. For example, you must have noticed that we don’t use the flour bought from the vendors directly for cooking chapatti. We use certain separation techniques in order to separate the flour from the impurities attached to it.

We generally use sieve plates for the separation of flour from the bran particles or other impurities. These sieve plates allow the fine flour particles to pass through the holes of the sieve plate while the bigger impurities are unable to pass through it and remain on the sieve. This method of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles.

It is used in flour mills or building sites. Impurities such as husks and stones are extracted from wheat at flour mill. They remove pebbles and stones from sand through sieving.
