6 Separation of mixtures - yellowreef

The method of magnetic attraction uses the basic principle of magnetism to separate a mixture of magnetic and non-magnetic substances. Bringing a magnet near such a mixture allows the magnetic substances to be attracted to the magnet. For instance, a magnet can be used to separate iron from a mixture of iron and non-magnetic substances.

Demonstration of Performance Timing of Magnetic Separation

The timing of magnetic separation is an important parameter to consider when using a simple button magnet for dead cell removal. When magnetic separation is too short, all the dead cells are not removed. When magnetic separation is too long, the live cells begin to settle to the bottom of the tube lowering the recovery of live cells. Figure 1 ...

Drum Separator - an overview | ScienceDirect Topics

The removal of "tramp" iron from feed belts can also be regarded as a form of low-intensity magnetic separation. However, tramp iron removal is usually accomplished by means of a magnetic pulley at the end of an ore conveyor (Figure 13.12) or by a guard magnet suspended over the conveyor belt (see Chapter 2). Tramp iron removal is important prior to crushing and …
