principles of classification

The principle behind this technique is the differential adsorption of the various components of a mixture between two different phases that are as follow..

The generator is an application of electromagnetic induction. It works on the principle that when a wire is moved in a magnetic field, then the current is induced in the coil. A rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horse shoe type magnet...

Difference in the wetting properties of the ore and gangue particle..

The coarse particles of the solid being heavier than the liquid (usually water), settle down due to gravity. The clear upper layer of the liquid is then gently poured out into another container. Settling down of the coarse particles due to the effect of gravity is called sedimentation. The mechani..

Liquids evaporate at all temperatures. Evaporation becomes faster at higher temperature..

Particles with higher density settle to the bottom while the lighter particles are separated through various processes such as winnowing (grain separation) and washing (panning of gold in the river bed..
