explain magnetic separation method in detail
Answers
=>Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet.
=> The working principle of magnetic separation is that materials which is going to be elected bearing the force of magnetic and other mechanical (such as gravity, centrifugal force, friction, medium resistance, etc.) together, in the sorting space of the magnetic separator.

Answer:
1.The magnetic separation process is based on the
differences in magnetic properties of the ore
components.
ii. This method requires an electromagnetic
machine which consists of a nonmagnetic
conveyor belt moving over two rollers, one of
which is magnetic in nature while other is
nonmagnetic
3.Powdered ore is dropped over the moving belt
near non magnetic roller. Two collector vessels
are placed below magnetic roller.
iv. The nonmagnetic particles are carried further
along with belt and fall in the collector vessel
placed away from magnetic roller. At the same
time, the magnetic portion of the ore is attracted
by the magnetic roller and falls in the collector
vessel near the magnetic roller.
E.g. Cassiterite is a tin ore which contains
mainly the nonmagnetic ingredient, stannic
oxide (SnO2) and the magnetic ingredient,
ferrous tungstate (FeWO4). These components
of cassiterite are separated by magnetic
separation method.
