Paterson & Cooke’s laboratory services provide a full range of test capabilities of mineral processing, tailings management, mine backfill and long distance slurry pipeline applications.
Our test capabilities include material and clay characterization, rheology, pipe loop tests, thickening, filtration, hydro-cyclones, tailings deposition, filter cake conveyability, and mine backfill characterization.
The laboratory facilities are located in Cape Town, Johannesburg, Santiago, Denver and Sudbury.
Gold Tailings Paste Cyclone Test Work
Pilot cyclone simulation test work covering a range of pressures and cyclone geometries, to generate a particular underflow particle size distribution optimal for paste backfill. The work included a full paste backfill binder strength study. This work provided many of the necessary parameters to facilitate efficient commissioning of the paste backfill plant.
Waste Water Treatment Plant Sludge
The impact of adding a waste sludge stream to tailings on thickener and filtration performance. The sludge precipitates alter the water chemistry enough to cause notable changes in performance parameters, some beneficial and some detrimental. By looking at the whole process and having the capability to experimentally verify each individual process we were able to guide our clients in making the best decision of their project.
Oil Sand Classification
The experimental study explored techniques for efficiently classifying a process stream containing air, fine and coarse solids, bitumen, and water.
