• Decantation – It is used to separate a mixture of liquids from heavy particles like water and sand.

• Filtration – It is a method that is used for separation of Liquids from solids that are not soluble in liquids, eg:- separation of sand and water using filter paper, or common filter at home.

• Centrifugal method- This method is commonly used for separating two liquids that are of different densities like milk from cream.

• Evaporation- The method is commonly used for separating water and soluble solutes like sugar or salt by heating.

Apart from this, distillation, decantation and crystallization are also methods that are commonly used for separating mixtures from pure substances.
