Read MoreThe term ‘filtering’ is generally used when the mixture contains a solid and a liquid, for example sand and water. When a sieve is used, the process is usually referred to as sieving. For example, a mixture of sand and gravel is separated using a sieve and works because the gravel particles are much larger than the sand particles. When a
