The electromagnetic method uses a mass spectrometer, or spectrograph, to send a stream of charged elemental particles through a strong magnetic field and allow the separation of isotope by mass. In gaseous diffusion molecules of a lighter isotope would pass through a porous barrier, and become isolated from those of a heavier isotope.

Separating a soluble substance from a liquid is called evaporation. A solution of salt dissolved in water can be separated by boiling the solution until all the water has evaporated. The salt will be left behind. If the water vapour was collected, it could be cooled to form water again.

Ans. Sieving is the method to separate particles of different sizes. Undesirable particles can be separated from grains by this method. The size of holes in the sieves depends upon the size of the particles. In cashewnut factories, the cashewnuts of different sizes are separated, by sieving.

Ans : Sieving is the method of separation of fine particles from bigger particles by allowing the finer particles to pass through the holes of a sieve, leaving the bigger particles in the sieve itself. It is generally used in homes to separate flour from impurities such as pieces of stone, stalk, and husk. It is also used at construction sites to separate sand from small stones. : How will ...

Industrial methods of particle size separation based on sedimentation or on elutriation. Wet sieving is more efficient than the dry process, because particles are suspended readily and passing easily through the sieve with less blinding of the meshes. II.

Sieving is defined as a method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes. Thus, it cannot separate two substances in a mixture which have the same size. For example, it cannot separate a mixture of chalk powder from flour. Frequently Asked Questions – FAQs

WhatsApp Dry sieving is the preferred method for the size range between 40 µm and 125 mm. However, the measurement range is limited by properties of the sample such as a tendency to agglomerate, density or electrostatic charging. VIBRATORY SIEVING . The sample is thrown upwards by the vibrations of the sieve bottom and falls back down due to gravitation forces. The amplitude indicates the vertical ...

The separation techniques of sieving are mainly used in a flour mill to separate impurities from wheat before grinding it. Sieving removes impurities like stones, stalk, and husk that still remain after threshing and winnowing. The sieve only removes particles of impurities that are larger than the pores in the sieve. Therefore, we can design the sieve according to our need.
