Sedgman – GEMCO Fine Sands Dewatering Facility & Port Stockpile Building

Groote Eylandt, Northern Territory, Australia

Sedgman was engaged to design and construct a sands beneficiation plant, port stockpile expansion, and other associated infrastructure at BHP Billiton’s GEMCO facility. The plant aimed to increase the capacity of the existing concentrator plant by reprocessing ore from tailings stockpiles.

Walz Group was contracted by Sedgman to provide all structural, mechanical and piping installation services, and construction works required to execute the project.

We provided construction services for all areas of the development, including the concentrator, tailings dam, and the port stockpile. These works incorporated the installation of around 700t of structural steel, including guards, pulley frames, and conveyor galleries. Mechanical installation comprised idlers, pulleys, drives, scrapers, belts, dump hopper, product bin, chutes, sump pumps, transfer pumps, process water pumps, return water pumps and numerous modifications to the existing plants. The piping component included installation of 1,500m of piping plus 2,400m of small bore piping.
