Methods of separation:
Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be colored, especially pigments.

5. Crystalisation
6. Magnetic Attraction
7. Paper Chromatography
Evaporation
Evaporation is the process by which water is converted from its liquid form to its vapor form and thus transferred from land and water masses to the atmosphere.
Filtration
Filtration is a technique used either to remove impurities from an organic solution or to isolate an organic solid.
Distillation
Distillation is the process of heating a liquid until it boils, capturing and cooling the resultant hot vapors, and collecting the condensed vapors. 
Fractional Distillation
Fractional Distillation is the process of separating a mixture of two miscible liquids (liquids that mix in all proportions) with different boiling points. 
Crystallization
CrystallizationCrystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. Crystallization is also a chemical solid-liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.
Paper Chromatography
Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be colored, especially pigments.
