The Reading Rare Earth Magnetic Drum (RED) uses a unique 5 pole magnetic element to generate a field intensity in excess of 0.7 Tesla on the drum skin. The magnetic element design affords the maximum field gradient and the 5 poles enables additional cleaning of the magnetic stream. This gives a very selective separation at high throughputs compared to alternative magnetic separators.

Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health ...

Ores are typically coarse-crushed (75mm) but may show recovery of 70% or better at run- of-mine sizes. The largest of the northern Nevada heap leaches (Carlin, Goldstrike, Twin Creeks) treat this type of ore. Unoxidized ore contains gold locked in sulfides, and also contains organic (carbonaceous) components, which absorb the gold from solution.
