The Multi-Gravity Separator (MGS), a new fine-particle gravity equipme
nt that has recently appeared on the market was tested in order to eva
luate its potential. In the first instance, the influence of its diffe
rent operating parameters an the quality of gravity separation were st
udied using a synthetic ore. This revealed the dominating role of thre
e parameters: speed of rotation, shake frequency and shake amplitude.
The MGS was then tested with a natural tungsten ore, which corroborate
d the results obtained with the synthetic ore. Finally, in order to as
sess the contribution that this new equipment represents in relation t
o other types of gravity separator, a comparative performance study wa
s made between the MGS and a Fines table.
