Various physical methods are utilized to separate heterogeneous mixtures based on their differing properties. Centrifugation uses rotational force to separate components based on density.
It is a method by which solids can be separated from liquids of different density by means of a rotating force.
Separación magnética:(Magnetic separation):
It is a physical process, which serves to separate two objects (in which one must be ferrous or have magnetic properties and the other not) through the use of separators as magnets.

Topic principal
Subtema
Decantación:(Decantation):
Decanting is a physical method used for separation of mixtures, it is used to separate a solid from one or two liquids, one denser than another that will occupy the bottom of the mixture. It is an important process in the treatment of wastewater.
Sedimentación:(Sedimentation):
It is the process by which materials transported by different agents and from erosion and weathering of rocks are deposited or precipitated, becoming sediments.
Filtración:(Filtration):
It is the process of separating solid particles from a liquid using a porous material called a filter. The technique consists in pouring the solid-liquid mixture that is to be treated on a filter that allows the liquid to pass but retains the solid particles.
Tamizado o criba:(Sieving or sieving):
Screening or screening is a mechanical method to separate two solids formed by particles of different sizes. It consists of passing a mixture of particles of different sizes through a sieve, sieve or strainer tool (depending on the use they can be metallic, vegetable-woven- or nylon).
