Abstract
A separator (1) for separating dense particulates from slurry includes a sealed housing (2) enclosing a submerged screen bed (33) which allows dense particulates to fall into a hutch (6) from which they may be discharged. The housing has a slurry inlet (4) arranged to deliver slurry to a sump (3) which directs slurry to flow radially over the bed. An annular cavity (23) formed between the housing and bed receives tailings flowing off of the top of the bed. An outlet (7) from the annular cavity allows discharge of the tailings, and a liquid inlet (30) to the hutch provides an upward flow of liquid through the bed. The bed is agitated to assist passage of dense particulates.
