• High G forces separate solids from liquid – no filter cloth.

• Not a batch operation - feed slurry continuously & uninterrupted.

• Fully automated – no dedicated operator needed.

• Lower CAPEX & OPEX and significantly smaller footprint than pressure filters.

Alfa Laval Solid Bowl Centrifuge:

– Dewater fine tailings and move towards dry disposal

– Eliminate tailings dams and risks asscoicated with it

– Recover water

– Reduce rehabiliation costs

Lab Testing

Slide 11

• Spin Test with a lab centrifuge

• Alfa Laval P1-100 skid mounted SBC

www.alfalaval.com

On-site testing – P2-405 SBC

• Capacity: Roughly 5 - 20 m3/hr, depending on feed solids concentration

• Solids Load: Roughly 3 - 10 dry t/hr, depending on solids density and type

Slide 12


On-site testing – Full Scale P3-10070• Capacity: 150 to 180 m3/hr,

depending on feed solids concentration

• Solids Load: Roughly 60 to 70 tonnes/hr dry cake, depending on solids density and type
