The Tailings & Mine Affected Water cluster is a highly social value focused group. The cluster has a broad range of industry stakeholders, all of whom have the goal to develop, promote and advance commercial solutions for tailings and mine waters.

As a cluster, the Tailings TeQ group demonstrates unified capability, provides clarity on problems, opportunities and capability for resources clients and tackles the key problems of tailings and mine water. Through addressing and solving legacy issues (locally, domestically and internationally), strengthening existing partnerships and raising awareness within industry reference groups and government, the Tailings TeQ cluster will help you create business opportunities and solutions. Successful clusters have impact far beyond the participants. Our industry, research institutes, education facilities and broader community all benefit from strong clusters.

The clusters’ vision is to be the “go to” group for Tailings and Mine Affected Water Problems. To do so, we will develop and promote collaborative capabilities in tailings technologies and mine affected water challenges through:

  1. Establishing a group charter
  2. Mapping of our capability
  3. Map near term opportunities
    • Starting small & work bigger
  4. Build trust
    • Work on reciprocity
    • Repeated successful transactions
  5. Set expectations – Willingness to partner
  6. Identify individuals who need help within industry
  7. Share success stories
  • Tailings dam design and construction
  • Water-efficient technologies
  • Mineral processing innovation
  • Progressive tailings rehabilitation
  • Water recovery and treatment
  • Secondary mineral recovery
  • Landform rehabilitation
  • Restoration of land use
  • Mined land repurposing
  • Monitoring and sensing
  • Tenure, legal and social performance

Water reclamation and reuse

Mine Water Solutions 

A large number of mines in the world are located in sensitive environments with shared water resources. Sensitivity can be based on cultural or economic aspects of the surrounding environment. Some examples are; water assets such as the Australian Great Artesian Basin and the Atacama Desert in Chile and Peru that are accessed by multiple users including agriculture and traditional land owners.

Mines must incorporate water treatment solutions that are efficient, contribute to urban, agricultural or natural supplies, allow for ecological restoration and include monitoring. They must also consider fluctuations in their water supply and contaminants. With a range of specialists, the Tailings TeQ group offers solutions at every step of the process: in the evaluation, design, construction, and operation of mine water treatment. We have leaders in the application of emerging technologies that are needed for challenging treatment requirements.

As resources clients increasingly approach water holistically, our group has responded by taking a collaborative approach to the management and treatment of mine water including mine drainage and process water. As a technology-neutral group, we have no vested interest towards any particular water treatment technology. This allows us to create site-specific treatment processes that are the best solutions for the application.

Process water treatment engineering

  • Conventional lime neutralization
  • High-density sludge
  • Iron co-precipitation of metals and metalloids
  • Sulphide precipitation of heavy metals

Advanced treatment design

  • Membrane Separation
  • Advanced Oxidative Processes
  • Biological Nutrient Removal
  • Ion Exchange
  • Passive mine water treatment
  • Submerged combustion evapoconcentration

Other treatments

  • Cyanide, thiocyanate, and ammonia treatment
  • Active/passive hybrid treatment systems for beneficial reuse
  • Treatability testing and process optimisation
  • Tailings dam remediation and treatment provisions
  • Membrane based water treatment, including; Reverse Osmosis, Nanofiltration & Ultrafiltration
  • Natural and engineered wetland treatment
  • Residuals management

In areas where water supply sustainability is a concern, water reclamation and reuse enables operators to be able to link the use of locally available water resources, by utilising reclaimed water, non-potable water these needs can be met. In doing so, it will improve the sustainability of aquatic ecosystems by decreasing the diversion of available freshwater.
