Home Tailings

Tailings Management

Our Tailings Group (formerly Australian Tailings Consultants) has built an international reputation encompassing all aspects of mine tailings management, including tailings testing and characterisation, thickening and dewatering, transport, storage and embankment design, technical assistance during construction, surveillance and auditing, closure and water management. The company is actively involved in continued research into tailings behaviour, primarily through support of post-graduate studies supervised by world-class scholars.

The effective management of mine tailings follows the complete mining life cycle and consists of several distinct steps, namely:
  • Scoping and feasibility studies
  • Geotechnical investigation and tailings characterisation
  • Detailed design
  • Construction
  • Ongoing operations
  • Closure and site rehabilitation

*See above illustration for further detail of each stage.

Clients can partner with ATC Williams at any stage of the mining life cycle. We offer a large range of services from conventional to tailor made innovative solutions, using a mix of traditional and latest technologies, including thickened and filtered tailings. Our experience covers a wide range of ore types, including but not limited to bauxite / red-mud, coal, copper, diamonds, gold, iron-ore, industrial minerals, lead / zinc, mineral sands, nickel, phosphate, uranium, washed sand and dredge residues.

ATC Williams pioneered the introduction of the Central Thickened Discharge System in Australia and is an acknowledged world leader in this method. We operate a NATA accredited testing laboratory in Melbourne, to carry out specialised testing procedures of mine tailings. We also have an extensive suite of in-situ testing and investigation techniques, as well as a range of leading software packages for the analysis and design of tailings storage facilities.

Over the years, ATC Williams has developed close working relationships with experts in allied fields such as thickening and filtration technologies, seismic risk studies, in-situ testing for liquefaction analysis and geochemical testing.
