magnetic separation of ore in metallurgy

Magnetic separation : ALS

Magnetic separation exploits the different magnetic properties in ore bodies to retrieve target minerals from gangue. The process utilises the competition between gravitation, centrifugal and friction forces, magnetic forces, and inter-particle attraction or repulsion. All magnetite ore bodies will require some magnetic separation investigation.

Metallurgy Definition & Process Principles of Metallurgy

Magnetic separation: This method of metallurgy is used when either the ore or the impurities are magnetic in nature. For example, magnetic ores like pyrolusite (MnO 2) and chromite (FeO.Cr 2 O 3) having a difference in the magnetic properties of the ore and gangue particles. In this method, the ground ore

Metallurgy Terminology, Types of separation or

The denser ore particles settle down in the grooves and lighter gangue particles are washed down by water. (ii) Magnetic separation method . Principle: The magnetic properties of the ores form the basis of separation. When either the ore or the gangue is magnetic, this method is employed. e.g., Tinstone SnO2, the ore of tin.
