An Opportunity to Make a Difference
The green economy, digital revolution, improved health and living standards all depend on metals supplied at a minimal environmental cost. However, the declining grade of the more accessible minerals, increasing complexity of mineralogy, and the growing need to extract the minerals from deeper mines, have reached a tipping point, making current practices technologically, economically, and environmentally unsustainable.
The Centre will develop transformational technologies for enabling a competitive and environmentally sustainable future for Australia’s minerals industry through:
- reduced environmental footprint
- significant reductions in energy and water use
- higher resources recovery
- future leaders to support the sector
This Centre will transform the minerals industry, establishing a new generation of research leaders to support the innovation needed in creating a green economy for future generations.
Our growing need for new technology imposes extraordinary demands for minerals extracted from the earth. Almost everything today is either made from minerals or reliant on mineral production: electric vehicles, whitegoods, laptops, healthcare and medicine.
More than 60 different metals are required to make a smartphone including gold, copper, aluminium, silver, zinc and lead. Rare earths provide smartphones with their functionality, to vibrate or even to generate the colour display. 
Metals are critical to providing essential medical technologies. Copper is found in MRI scanners and is vital in medical equipment due to its anti-microbial properties. Titanium is used for surgical equipment due to its bacterial resistance; and silver is present in some antibiotics for accelerating the healing process. 
Enabling Transformation for a Greener Economy
The recovery and concentration of particles of high metallurgical value, known as beneficiation, is based on relatively mature paradigms. The industry has evolved gradually over more than a century, however flotation processing rates per unit of vessel area have not increased during that period. The waste, which often requires massive tailings dams, results in excessive water consumption, and risk of a catastrophic tailings breach.
With a projected global population of nine billion by 2050, and the demand for minerals set to soon outstrip supply, the industry faces an unprecedented challenge.
This Centre aims to transform the industry through research programs focused on three goals:
Energy and Water
To double energy and water productivity in the mining sector by 2030, maintaining the drive towards the ‘zero- emission mine’.
To reduce loss of high value metals during minerals processing by 90%, increasing the concentration of recovered products used in metals refining.
To establish a new generation of scientists and research leaders in minerals beneficiation to support the innovation needed to sustain the Australian industry.
We will establish transformational technologies which will deliver the basic elements needed to address the need for unprecedented change to the practice of minerals processing. Our programs and projects have three eco-efficient objectives.
The process of grinding rocks down to ultrafine particles is the single biggest consumer of energy in the minerals industry. The introduction of new technologies provides the opportunity to reduce the use of energy and water by as much as 50%. Such new technologies include new crushing modes to achieve fracture along the mineral grain boundaries, novel reagents and new separators to remove the waste rock at a coarser size.
100% Water Recycling
We will apply our advances in ‘fast, efficient beneficiation’ of fine particles to solid-liquid separation in order to increase product recovery and to recover waste solids, reducing water wastage and increasing water productivity. We will then recover targeted solids and exploit hydrophobic interactions to enhance de-watering.
Maximising Resource Efficiency
New transformational technologies will deliver a 10 – 100-fold increase in separation speed of fine particles. This will reduce the footprint and cost of the processing plant and promote a step change increase in the grade and recovery of the valuable minerals for metals production.

Physics of novel system hydrodynamics
Maximising the robustness, efficiency, and speed of separation are critical elements of any transformational mineral beneficiation technology. This will be achieved by building knowledge and understanding of a broad range of novel hydrodynamic systems to determine the potential to approach the theoretical limits of separation, traversing the particle size range of interest.

Chemistry of novel hydrophobic and selective interactions
For the last 100 years, high value minerals have been ground to a fine particle size and then separated by adsorbing reagents, known as collectors, onto the mineral surface to make the minerals hydrophobic, and attraced to bubble interfaces. New approaches are needed to exploit the full potential of hydrophobic interactions for i) separating coarser particles, ii) ultrafast and selective separations, and iii) separating almost all the liquid from the mineral particles at the end of the separation process.

New engineered biopolymers and synthetic polymers
Application of polymers as collectors in minerals processing is relatively new. Polymers have traditionally been used in flotation to suppress recovery of certain minerals, while high molecular weight polyacrylamides have been the foundation of flocculation in solid-liquid separation. New approaches to the synthesis of more effective and cheaper polymers are now available for exploitation in minerals processing. These could lead to better concentrate grades, higher mineral recovery and new polymers to achieve improved water recovery.
