In December 2009, Built Environs completed construction of a $12.5 million storage and shipping transfer facility for heavy mineral concentrate at Port Thevenard, near Ceduna, South Australia for Iluka Resources Limited.
The completed facility receives heavy mineral concentrate by road from the Jacinth-Ambrosia mineral sands deposit (about 270 km northwest of Ceduna) and then transfers the material by three conveyers and chutes to ships berthed at the existing wharf.
The work drew on civil, mechanical, structural and electrical engineering disciplines, and involved construction of a 50,000 t capacity heavy mineral sand storage area, construction and commissioning of a conveyor belt feed system, provision, installation and commissioning of site electrical requirements, construction of new sealed access roads, and mains water and stormwater works.
The conveyor belt feed system work included transfer towers, wet dust suppression, head chutes and a high level walkway, and required tying-in of the system with the existing Australian Barley Board (ABB) and Gypsum Australia conveyors.
The electrical works included stock pile and conveyor switch rooms, facility cable support systems, field devices and cabling, facility lighting, control systems and a security access system.
This was an exciting project for a new client with other projects in the pipeline and drew on Built Environs’s experience with mineral processing works at Prominent Hill and Roxby Downs in South Australia and Ravensthorpe in Western Australia.
The Built Environs engineering capability that delivered this project is now provided by the South Australian engineering office of parent company McConnell Dowell, offering clients access to both the expertise of the former Built Environs engineering teams and the international experience of McConnell Dowell.
