separating mixtures through screening

Anderson School District Five / Homepage

Sifting Sifting is used to separate smaller solid particles from larger solid particles. • For example, the mixture of different sized solid particles can be put into a container that has a screen material at the bottom with holes of a certain size. • When the mixture is shaken, the smaller particles go through the screen leaving the larger

Filtration - Wikipedia

Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. Oversize particles may form a filter cake on top of the filter and ...
