Generally, magnetic separators are classified as low or high intensity and whether they work in wet or dry applications. An example of a concurrent low-intensity wet magnetic separator is shown in figure 20. In concurrent separators, slurry flows in the same direction as the rotation of the drum surrounding the magnets.

The wet magnetic separator has a wide particle size and a lower particle size of 20um. Therefore, when the zircon particle size is fine, the wet magnetic separator is more suitable. Because there are many associated minerals in zircon sand, it is necessary to combine gravity separation, magnetic separation, flotation and electrostatic separation.

The results indicated that gravity concentration and flotation were the most effective processes, whereas magnetic concentration and electrostatic separation were effective only for supplementary separations. It was recognized, therefore, that the effectiveness of beneficiation of the pegmatites depends upon a combination of processes.

The Gold Cube has a built in design to eliminate surface tension called the "G-Force Separator" which forces everything underwater and under a gate, breaking surface tension and forcing the heavier gold to the bottom of an axial trough. This force is gravity and hydraulic pressure making it impossible for the gold to float or sail.

When ground ores are fed into the suspension, the gangue particles, having a lower density, tend to float and are removed as tailings, whereas the particles of valuable minerals, having higher density, sink and are also removed. The magnetite or ferrosilicon can be removed from the tailings by magnetic separation and recycled.

Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.
Get priceHighly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized. The reagents used for flotation are generally not toxic, which means that tailing disposal costs are low.

Jig Feed In coal washing jigging is practiced on unsized material as coarse as 175 mm (7 in). In metal-milling practice jigging is now seldom employed on material coarser than 20 mm (e in). Float-and-sink methods have largely superseded jigs as a way of concentrating metallic ores in the minus 75 to plus 10-mm (3 to plus a-in) range.
