- 1Sieving Sieving involves separating a mixture based on different sizes of components. You can separate different substances such as: small sand grains and flour.
- 2Evaporation This method is used for recovering dissolved solids from solutions. For example, sea salt is the result of the evaporation of sea water.
- 3Distillation This method is similar to evaporation, except that the evaporated substance, known as the distillate, is collected. For example, is used in producing petrol, alcohol and perfumes.
- 4Decantation Decantation involves separating a dense, insoluble substance from a heterogeneous mixture. For example, if we mixed sand with water in a beaker, the sand would not dissolve, but would settle to the bottom, forming a sediment layer.
- 5Crystallization This method is the process of formation of solid crystals from solution, melt or by deposition directly from a gas phase. For example, different types of candies can be a result of this method.
- 6Filtration Filtration is a special form of sieving that separates very fine solid particles from liquid or gas mixtures. For example, filters are used in a variety of applications to keep air and water free from minute dust and other particles.
- 7Magnetism This method is specifically used for separating magnetic materials, such as iron, from non-magnetic materials, such as soil and plastic. Is used in the mining and recycling industries.
- 8Paper Chromatography It separates mixtures based on their differing levels of attraction to two different substances. For example, drug testing of urine and blood samples.
- 9Centrifuging Spinning tubes at very high speeds can be used for separating solid particles from liquids, or for separating non-miscible liquids. For example, separation of fat from milk and the separation of different components in blood.
