Sieving

Is the method of separating solid of different size

And it’s use in gari production

Recantation

Use to separate a mixture of liquid and denser particles which separate into two distinct layers on standing

Filtration

Use for separating insoluble particles from liquid through the pore of filter paper

Example suspensions of chalk dust in water

Evaporation

Use to separate dissolved solute from a solution by heating the mixture to dryness

Distillation

Used to recover a solvent from a solution

Fractional distillation

Use to separate a mixture of two or more liquid of close boiling point

e.g natural gas, petrol, kerosenes, gas oil, heavy oil and bitument they can be recovered to their pure form by fractional distillation

It can so be used to separate a mixture of benzene methyl benzene and liquefied air into pure nitrogen, oxygen and noble gas
