Magnetic Attraction

Magnetic Attraction is used to separate magnetic materials from not-magnetic materials.

Filtration

Filtration is used to separate an insoluble solid from a liquid solid mixture. This mixture is also known as a suspension.

Filtration is used quite commonly in our everyday lives. For example, the filter in fish tank and air conditioner units, washing of vegetables using sieves and making tea using teabags.

Evaporation

Another method to separate mixtures is evaporation till dryness. It is used to separate dissolved solids from a solid-liquid mixture. This method is only effective if the solid that is dissolved has a high melting point. This means that it will not melt or decompose when heated.
