Somincor, Portugal: Feasibility and detailed design of a new underground mine dewatering and pumping system. The design includes lamella thickening and positive displacement pumping to treat and then remove 190 m3/hr of water from 800 m below surface.

Umm Wu’al Phosphate Project, Saudi Arabia: Investigation into the conveyability of filtered tailings in conjunction with the transportable moisture limit.

Leach Residue: Rheological characterization of a high temperature (90⁰C) and low pH (less than 1.5) leach residue material.

Clarification/Thickening and Filtration of Calcine Baghouse Dust: Test work involved finding optimum coagulant and flocculant balance, optimum flocculant mix energy levels, definitive thickening and filtration sizing parameters at controlled pH and elevated temperature (40⁰C).

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 … Read More

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 … Read More

West African Tailings Flow Behaviour Test Work: Large scale loop tests were conducted to evaluate the minimum flow requirements for the transport of a fine tailings from a West African Mine. The objective of the test work was to determine the the implications on the existing pipeline installation of operating with a stationary bed. The … Read More

Nautilus Minerals, Australia: Analysis and review of the high pressure pump and pipeline requirements for the Solwara deep sea mining project at depths of up to 2000 m.

Ngqura Harbour Sand Bypass System, South Africa: Commissioning of water pumps, jet pumps, sand transport pumps and pipeline as well as modification of the control system. We provided further design and engineering services for system modifications, improvements and maintenance issues. We also conducted a study for the expansion of the existing system.

Durban Harbour Sand Bypass System, South Africa: Design, engineering, specification and commissioning of a temporary sand bypass system for the Durban Harbour Widening Project. In addition, Paterson & Cooke completed a pre-feasibility study and detailed design for the new sand hopper and beach feeding system for implementation after the completion of the harbour widening project. … Read More
