Did You Notice to Configuration of Magnetic Separator

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold. It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. A criteria called as concentration criterion is commonly used for this purpose. But did you notice to the configuration of magnetic separator?

These processes can be classified as either dense medium separation or gravity separation. The difference between the two that gravity separation does not use a dense medium to operate, only water or air. Dense medium separation can be performed with a variety of mediums. These include, organic liquids, aqueous solutions, suspensions in water and suspensions in air. Of these, most industrial processes use suspensions in water. The organic liquids are not used due to their toxicity and difficulties in handling. The aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and the suspension in air is used in water-deficient areas, like china, where sand is used to separate coal from the gangue minerals.

The configuration of CTB 1530 magnetic drum separator is ib the following: drum of the electromagnetic separator is designed in such a way that only half of its side is magnetized and the other side is not magnetized. The permanent magnetic drum consists of stable permanent magnetic assembly having uniform and everlasting magnetic field through the entire width of the drum, which is effective over approximately half the drum circumference.
