- 1SIEVINGSieving is a physical mechanism of particle removal, where a particle is denied access through a pore smaller than the particle itself. Used to separate solid mixtures which have components of different sizes.
- 2EVAPORATIONIs a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. Soluble substances can be separated back out from their solution.
- 3DISTILLATIONThe action of purifying a liquid by a process of heating and cooling. Liquid mixtures can be separated because different liquids have different boiling points.
- 4DECANTATIONIs a process for the separation of mixtures of immiscible liquids that have different densities or of a liquid and a solid mixture such as a suspension.
- 5CRYSTALLIZATIONCrystallization is a technique used for the purification of substances. A separation technique to separate solids from a solution.
- 6FILTRATIONFiltration is technically defined as the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of a membrane, called a filter.
- 7MAGNETISMIt is a property of certain substances which pull closer or repel other objects. Minerals can be easily separated from other minerals.
- 8PAPER CHROMATOGRAPHYUses paper sheets or strips as the adsorbent being the stationary phase through which a solution is made to pass. A method of separating dissolved chemical substances across the sheets of paper.
- 9CENTRIFUGINGIs sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions.
