Electromagnetic Separation of Wolframite
The first magnet removes the strongly magnetic iron compounds and the second the wolframite, while the tin is contained in the nonmagnetic tailing. The tungsten concentrate and the tin product from the separator are both reconcentrated to eliminate waste. The raw ore yields 0.378 per cent. tin and 0.72 per cent. tungsten.
Concentration of Ores
Explanation: Electrostatic separation is a method used for concentration or separation of ores when they are good conductors of electricity. It is based on the principle that when an electrostatic field is applied the ore particles, which conduct electricity, get charged and get repelled by electrodes having same charge and all thrown away.

Cassiterite is concentrated by:a) Levigationb) Electromagnetic
The lighter gangue particles are washed away with a stream of water while the heavy ore particles settle down. This method is generally used for oxide ores of iron and tin. >b) Electromagnetic separation: It is a process in which valuable minerals that are attracted by a magnetic field are recovered from a mixture using a magnetic force.
Which of the following cannot be concentrated by electromagnetic
Electromagnetic separation is used to concentrate an ore when either the particles of the ore or the impurities present in it are magnetic in nature. Chromite, magnetite and pyrolusite have magnetic nature and are separated from their non-magnetic gangue particles using this method. Zinc blende is concentrated using electrostatic separation or froth floatation.
Application of Electromagnetic (EM) Separation Technology …
Application of electromagnetic (EM) force to metal processing has been considered as an emerging technology for the production of clean metals and other advanced materials.

Electromagnetic separation is used in the concentration …
Electromagnetic separation is the method to concentrate the ore or to remove unwanted materials like sand and clay from the ore. Magnetic or electromagnetic separation is the technique based on differences in magnetic properties of the ore or gangue. The particles that are attracted with the magnetic field are separated out.
Bauxite is concentrated by:Chemical methodRoastingFroth …
The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N aOH will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.This method is called the chemical …
