Separation is the main step of ore concentration. Metal recovery and productivity largely depend on the separation process and methods. Based on the physical and chemical properties of ore like its grain size, shape, color, density, friction coefficient, magnetism, moisture and electric property, several process and methods are available.

Separating mixtures. 4. MagnetismMagnetism If one component of the mixture has magnetic properties, you could use a magnet to separate the mixture. Iron, nickel, and cobalt are all materials that are magnetic. Not all metals are magnetic: gold, silver, and .
Separating Mixtures. If you're short on time, you may want to take advantage of the boiling point of water, which is much lower than the boiling point of salt. By heating the water to its boiling point, you are allowing it to change from a liquid to a gas, eventually leaving all of the salt behind.
Magnetic separation method and washing with distilled water and absolute ethanol for several times is the deposit procedure . The reaction of coprecipitation is carried out by motor stirring under N2 and argon atmosphere and surfactant is also used [ 14, 23 ].
A phenomenological method is proposed for the reversible spectra to separate the relaxation processes of domainwall motion and magnetization rotation. The separation provides a method for measuring the static susceptibilities and the relaxation frequencies for the two reversible magnetization processes.

This method of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles. Sieve plates have meshed or perforated bottoms which allow only particles of a specific size to pass through it.
