1. Introduction. Classification is a method of segregating the particles of different sizes, shapes, and specific gravities into two or more products on the basis of their settling velocities in a medium of separation, which may be liquid or gas [1], [2].Depletion of the high grade ores, intricate association of gangue with ore minerals and the advent of …

Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those lesser ...

Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants. From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of low-grade sulfide copper ores.
