At Ausenco, we specialise in the design of tailings management systems including:
Ausenco has extensive experience in designing a variety of tailings storage facilities, including in difficult terrain and challenging climatic conditions. We have designed more than 100 tailings dams across the globe. Our track record includes tailings pipelines, storage dams and impoundments in wet and dry climates, at high elevations, in active seismic regions, and in remote mine locations.
Our projects include conventional surface deposition, submarine discharge (subsea or sub-lake), surface paste (high density tailings), cemented paste backfill (using the tailings for structural fill in underground mines), and dry stacking (surface disposal of filtered tailings).
We are at the forefront of the latest technologies and work with an exceptional team of geotechnical, hydrological, hydrogeological, environmental scientist and slurry process engineers to design optimum tailings management systems for our clients.
We have experience in Greenfield and Brownfield operations and frequently perform trade-off studies to determine the best technical/economic solution for the mine, with particular emphasis on water recovery and life of mine planning.
We have extensive expertise working with existing systems and making the necessary adjustments that are required as the operation matures.
This knowledge and experience ensures that we can successfully address a variety of client issues, including:
Ausenco’s tailings transport solutions include gravity flow, open-channel flow, energy dissipation, multiple pumps in series, and thickened paste disposal. We also offer our clients expertise in pipeline SCADA and telecommunications systems. Our specialties include developing SCADA solutions for remote locations—stand-alone, self-sustaining systems that require a minimum of local staff and maintenance.
