Apr 25, 2019 Sieving is used when two components of a mixture have different particle sizes. Sieving allows the fine particles to pass through the holes of the sieve, while the bigger particles remain on the sieve. For example, sieving of wheat flour, sieving of sand at construction sites.
Sep 25, 2013 Ways of separating mixtures 1. Separation of Mixtures Identify the different ways of separating mixtures. Determine how the different ways are used to separate mixtures. Identify the ways in which Hand Picking, Threshing, Winnowing, Sieving, Magnetic Attraction, Sublimation, Evaporation, Crystallization, Sedimentation amp Decantation, Loading, Filtration,
Some substances are easily separable just by taking out the impurities with hand. This method of separation is known as hand-picking. But some of them cannot be removed by hand, and we need some other methods of separation for such mixtures. For example In our house, our mother separates stones and insects from rice simply by hand. But in case ...

A mixture contains three different substances X, Y and Z. They are of the same size, cubical in shape and yellow in colour. X particles are very heavy, insoluble, non-magnetic and contribute 50 of the mixture. Y particles are very light, insoluble, non-magnetic and contribute 40 of the mixture. And Z particles are iron pieces.
