Since materials found in nature are mostly made up of mixtures of pure substances, to obtain them, from the composite substances it is necessary to separate them by a suitable method.
There are many processes for separating mixtures, but the method to be employed depends on the material conditions for using it and the type of mixture to be separated.
Have you thought about how to separate some mixtures that are found in your daily life?
This requires first observing whether the mixture in question is homogeneous or heterogeneous and then choosing the most appropriate process for separating it.
The most commonly used processes for mixing mixtures
1) Picking, Ventilation, Levitation, Sifting, Magnetic Separation and Flotation, used in the separation of heterogeneous mixtures consisting of two solid components.
Catation: It is a simple process of separating solids into a heterogeneous mixture. The grains or fragments of one of the components are picked by hand or tweezers.
Ventilation: Ventilation is used to separate less dense solids, passing through the mixture a draft that drags the lightest.
Levocation: a mixture of water is passed through the mixture and it drags the lightest.
Magnetic separationA magnet is passed through the mixture, if one of the components has magnetic properties, it will be attracted to the magnet.
