Paterson & Cooke’s skills and experience enable us to develop new technology for mining and mineral process applications, as well as design and supply specialised Pilot Plant facilities.
Our specialised products include the Vector® feedwell and HydroForce controllable feed dilution system to improve the performance of new and existing thickeners, as well as dewatering bins to separate coarse and fine slurry streams, novel fluidisers, flow splitters, and a range of purpose built backfill strength testing machines.
Four dewatering bins and fluidisers are fitted to the offshore diamond mining vessel, MV Mafuta. The bins receive feed from the sub-sea riser pipe that discharges through a Compact Splitter™ before splitting the flow to each bin. From the bin underflow, the fluidisers feed the material to the downstream process.
During 2016 and 2017 Paterson & Cooke supplied and commissioned four Vector® thickener feedwell and HydroForce dilution system on 50m and 70m thickeners at a major South African coal producer. The upgrade had a significant positive impact on the performance of the newly retrofitted thickeners.
Paterson & Cooke were responsible for the turnkey design and supply of a complete batch operated fly-ash paste plant. The major equipment includes ash loading stations, 20 m3 storage silos, paste mixers, control room and fully instrumented paste pump and pipeline system.
An extensive test campaign conducted at our Cape Town Slurry Test Facility in conjunction with the Client provided the basis for the development of a novel mineral processing flow sheet that was developed to pilot plant scale. The pilot plant was designed and built in South Africa and comprised several stand-alone containers that were re-assembled on site in Chile and commissioned.
