<span>Separating mixtures can be
done in many ways. One of these methods is the physical methods which include,
filtration, crystallization, distillation, and chromatography.
Since mixtures come in a lot of forms and
many phases, some of them cannot be separated through the first physical methods.
The methods of separating mixtures depend on the kind of mixture. Other common separation methods include
fractional distillation which is similar to simple distillation method, magnetism,
which is ideal for mixtures whose one
part has magnetic properties and separating funnel, an ideal technique used to
separate immiscible liquids..</span>
