Ranger Uranium Mine

GPA designed a reconfiguration of Energy Resources of Australia’s (ERA) process water pre-treatment plant as part of the Ranger Uranium Mine in the Northern Territory. The reconfiguration was to enable the implementation of the high density sludge treatment process. The project also included designing 15km of brine, permeate, and mine water pipelines.

ERA required the process water treatment model to be developed using the SysCAD process simulation package. GPA completed initial feasibility studies, followed by the detailed engineering design, construction and commissioning support for a new flocculent facility.

ERA had existing ultra-filtration and reverse osmosis capacity at Ranger. With the commissioning of the process water pre-treatment plant, an increase in water treatment capacity was required to treat both the pre-treated process water, and site pond water (mildly contaminated site run-off).

GPA designed and commissioned a new micro filtration and reverse osmosis plant to provide 5ML/d additional water treatment capacity. We also completed the engineering design and managed the equipment tendering, procurement and commissioning.

Our approach included containerising the plant equipment with integrated bunding and a strip drain that significantly reduced the volume of concrete required and thereby reduced site installation costs and time.

GPA placed great emphasis on personnel protection and when the design required overhead routing of hazardous dosing chemicals, GPA specified the novel design of transparent conduit to enable any leaks to be located without exposing operations staff to undue risk.
