INTRODUCTION
# Magnetic separation is a process
in which
magnetically susceptible material is
extracted from a mixture using a
magnetic
force.
#
Since 19th century magnetic
separation processes have been used
to concentrate and separate minerals.

APPLICATION OF MAGNETISM AS
SEPARATOR
Basically Magnetism is used for five distinct type of
separation :
CLASSIFICATION OF MAGNETIC
SEPARATOR
It can be classified according to the medium
in which the separation is made, the mode of
the presentation of the feed, the mode of
disposal of the products, & whether the
magnets are stationary or moving.
EDISON SEPARATOR
Edison separator consists of a
bar magnet . The ore as thin
streams falls in front of the
poles, susceptible particles
being deflected inwards &
nonsusceptible particles
continuing to fall undeflected.
This separator was not
wholly successful because of
inability of control flow of solid
in a thin sheet, & because of
lack of control over the speed
How it Works?
The processing materials enters the top of the
magnetic drum separator and flows across the
surface of the drum. The rotatory drum in the
magnetic field captures the ferrous tramps
whereas non ferrous falls free from the drum into
the cleaned material flow. As the drum rotates,
the ferrous metal so captured is carried past the
diverter and released outside of the magnetic
Types
field.
Magnetic drum separators are of different types
like:
Electro drum separators
Wet drum separators
Double drum separators
Applications
The magnetic drum separator is ideal for separating iron
particles from granules & powders It is widely used in the
following industries:
Glass
Ceramic
Chemical
Fertilizer
Plastic
Food industry
Iron and steel slag treatment
Reduced pyrite ash separation
Calcined ilmenite production
Metal powder production
Applications
Roller type magnetic separator finds applications in the
following areas like:
Glass industries
Abrasive refractory
Quartz cleaning
Upgrading of graphite
Recovery of metals from slag removal of ferro silicates
Chemical industries
Applications
Gravity magnetic separators have different industrial and
commercial usage. They are applied in industries like:
Food industry
Chemical industry
Grain processing industries
Pharmaceutical industries
Features
Wet drum magnets have high magnetic
recovery and
discharge.
The feed slurries recover the magnetics.
Available in single or multiple drum
applications.
Recover magnetic solids in as clean a magnetic
concentrate as possible .
Permanent magnet assembly eliminates coil
burn-outs .
The magnet / pole elements are bolted to a mild
steel
shaft.
The drum is made from thick stainless steel for
long
service life.
Applications
Glass industry
Chemical industry
Plastic industry
Mining industry
Food industry
Pharmaceuticals industry
Foundry industry
