EVOLUTION IN GRAVITY SEPARATION FOR ENVIRONMENTALLY FRIENDLY MINING

nnnn

In a world of limited water resources and rising costs to

nnnn

meet environmental requirements, the demand for new

nnnn

technologies to reduce outlay on the separation

nnnn

processes is increasing.

nnnn

The two major problems facing the industry are:

nnnn

• limited water availability in arid areas

nnnn

• environmental restrictions of both water supply and

nnnn

disposal of slurries

nnnn

In response to this, AKW A+V developed a new kind of dry

nnnn

gravity separator for fines. The recent breakthrough arose

nnnn

from the air fluidised bed, in combination with a specially

nnnn

developed sifter. Latest trials have confirmed its

nnnn

outstanding efficiency.

nnnn

The optimum working range is for grains less than 3mm.

nnnn

Trials have also shown good results are achievable with

nnnn

differences in density less than 0.3 g/cm3, e.g. feldspar

nnnn

and quartz. Capacities between 5-25 t/h can be attained

nnnn

with units of 1,200 mm width.

nnnn

AKW A+V can provide feasibility test work for all

nnnn

interested customers. Furthermore, we offer a mobile unit

nnnn

for on site test work.
