• Separation techniques are those techniques that can be used to separate two different states of matter such as liquids and solids.
• Separation processes or a separation method or simply a separation is methodology to attain any mass transfer phenomenon that convert a mixture of substances into two or more distinct product mixtures.
• Separation is an important asset to purify component of interest from a mixtures.

Magnetic Separation

• This method involves the separation of magnetic substances from non-magnetic substances by means of magnet.
• Takes advantage of physical property of magnetism, so it useful only for certain substances such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less affected, but the effect is still noticeable).
• This method involves the separation of magnetic substances from non-magnetic substances by means of magnet
