medium separation process. Chapter 1 of this report presents the history of the process which shows that a variety of materials have been used to make up a dense medium. The use of magnetite# however, soon became widespread owing to its magnetic properties which enable wet drum magnetic separators to recover it very efficiently from the process.

separators act as the drain and rinse screens of this process. The efficient magnetic separators ensure that minimum magnetite will report to the product or discard that goes to the desliming sections. Efficiency tests were done on the magnetic separators installed at Leeuwpan. The results obtained from the analysis of the magnetic separator ...

The cyclone underflow goes to the refuse D&R functioning identical to the clean coal screen. The magnetic separator concentrate returns to the media sump and the separator tailings go elsewhere. Gallons and gallons per minute (gpm) are the units of volume and flow used in the tables, but one can see the relationships intended without converting ...

One of its newest developments is the Hybrid Wet Drum Separator, which is expected to enhance magnetic recovery in heavy media circuits. The hybrid element uses ceramic material and rare earth magnets to …

1. ILMS should be mounted so that the magnet self-cleaning belt is at angle to the conveyor belt over which it is suspended.
2. The electro magnet is parallel to the conveyor belt over which it is installed.
