Good work Alistair Stephens - ARU should be heading to $3:00; but it is not !
The results can be summarised as follows;
In the sizing range from less than 5.6mm to greater than 2.8mm it is possible to
achieve a rare earths and phosphate separation from the gangue fractions range at
high recovery of REO and phosphate with significant mass rejection of waste.
o At a heavy media density of 2.84, the rare earths grade increases from
3.15% to 4.2% with a recovery of 96%, P2O5 increases from 13.6% to 18.4%
with a recovery of 97% with a mass rejection of waste of 28%.
In the sizing range from less than 2.8mm to greater than 1mm it is possible to achieve
a rare earths and phosphate separation from the fractions at high rare earths recovery
with significant mass rejection of waste:
o At a heavy media density of 2.84, the rare earths grade increases from
3.15% to 4.22% with a recovery of 94%, P2O5 increases from 23.6% to
32.5% with a recovery of 96% with a mass rejection of waste of 30%.
In the sizing of less than 300 microns it is possible to achieve a rare earths and
phosphate separation from the gangue at high rare earths recovery with significant
mass rejection of waste:
o At a heavy media density of 2.86, the rare earths grade increases from
2.67% to 3.94% with a recovery of 94%, P2O5 increases from 22.1% to
30.6% with a recovery of 94% with a mass rejection of waste of 32%.
The test work demonstrates that heavy media separation is effectively rejecting waste
material across all size fractions.
Arafura’s Managing Director, Alistair Stephens said “this is an excellent result that will
reduce operating and capital costs.
