Separation methods, then, can be defined as processes that change the relative amounts of substances in a mixture. In chemical methods, one may start with a completely homogeneous mixture (a solution) or a heterogeneous sample (, solid plus liquid); in the act of separation, some particles are either partially or totally removed .

Electrical and Magnetic separation: Electrolytes and non electrolytes, magnetic and non magnetic substances can be separated by this technique of separation using either electrical field or magnetic field.

Mixtures come in many forms and phases. Most of them can be separated, and the kind of separation method depends on the kind of mixture it is. Below are some common separation methods: Paper Chromatography This method is often used in the food industry. It is used to identify chemicals (coloring agents) in foods or inks.

Magnetic and NonMagnetic Substances The substances which are strongly attracted by magnets are called magnetic substances. For example, iron, cobalt, nickel and their alloys are magnetic substances.

Magnetic separation is also used to separate magnetic substances from waste water. Filtration is a technique that will separate a solid that has not yet dissolved in a liquid. Take a mixture of a solid and liquid and run it through a filter, the liquid will pass through the filter and you will be left with the sold.
