Learn various separation techniques with examples for different types of mixtures. Find out how to separate substances by handpicking, threshing, winnowing, sieving, evaporation, distillation, filtration, separating funnel and magnetic separation.
Sep 12, 2021 · Simple extractions are particularly useful for separations where only one component has a favorable partition coefficient. Several important separation techniques are based on a simple extraction, including liquid–liquid, liquid–solid, solid–liquid, and gas–solid extractions.
Sep 19, 2019 · Mixtures can be separated using a variety of techniques. Chromatography involves solvent separation on a solid medium. Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes.

This is a separation technique used to separate solids of different sizes. The mixture to be separated is first placed on a sieve having a mesh of a particular size. The solid particles smaller than the mesh size of the sieve will pass through the sieve whilethe bigger particles remain on the sieve. The method is extensively applied in the mining i...
This is a separation method used to separate immiscible liquids due to the difference in their densities. Immiscible liquids means liquids that do not mix together to form a uniform mixture but separateout into layers. Using a separating funnel, the denser liquid stays at the bottom while the less dense liquid stays on top, the tap is opened slowly...
This is a separation method used to separate insoluble particles e.g precipitates from a liquid. Examples are the suspension of chalk particles in water, sand, and water. The chalk suspension is poured onto the filter paper; the water passes through while chalk remains on the filter paper. The principle is that the solid must not dissolve in the li...
This is a method of separation used to separate salts that do not decompose easily on heating i.e salts that can withstand high heating. This method is suitable to separate a soluble solid from a liquid. When the solution is heated, the liquid evaporates leaving the solid behind. It is used to recover solid solute from solution. In this process, th...
This is an old and inaccurate method of separating an insoluble solid from a liquid. The mixture of the liquid and solid separates out in two distinct layers on standing. A lower solid layer and an upper liquid layer can be carefully decanted and poured out into a container. Examples of mixture that can be separated by decantation include sand and ...
This is a method used to separate mixtures that involve a substance that is able to sublime e.g camphor, iodine, ammonium chloride. Examples of such mixtures include impure NH4Cl, iodine, and Sulphur etc. The substance that is able to sublime can easily be separated from the other when the mixture is heated leaving the other behind.
This is a separation method used in separating miscible liquids with far apart boiling points example water (1000C) and ethanol (780C), Acetone (560C) and water (1000C), etc. For accurate distillation, the difference in boiling point must be up to 200C. Simple distillation can also be used to distill water from a salt solution. During distillation ...
This is a method used in separating miscible liquids with small differences in their boiling points e.g ethanol and octanol, also the fractions of petroleum can be separated using fractional distillation.
This is a method used in separating magnetic materials from non-magnetic ones. The principle behind this separation is that one of the materials must be magnetic. It is applied in mining industries in separating magnetic ore from non-magnetic ones. Magnetic materials include iron, nickel, cobalt, and steel.
Crystallization is a method used to separate salts that decompose easily on heating from their solutions. The salt solution is first heated to evaporate some of the solvents, the solution then becomes saturated. When the saturated solution is cooled, crystals of the salt begin to form. The salts are obtained purely as crystals containing water of c...
Learn how to separate mixtures of solids, liquids, and gases based on their physical properties using different techniques. Find examples, applications, and principles of each method with diagrams and explanations.
Learn how to separate insoluble and soluble solids, liquids and gases using different techniques such as filtration, evaporation and distillation. Find out how to distinguish physical and chemical changes with examples and diagrams.
Separation and purification, in chemistry, separation of a substance into its components and the removal of impurities. There are a large number of important applications in fields such as medicine and manufacturing. Since ancient times, people have used methods of separating and purifying chemical.
