New processing circuit designs, integrated simulation capabilities and operational control systems to exploit changes in grade and other physical properties resulting from Grade Engineered feed streams.

Coarse separation ‘unpacks’ in-situ mineralogy and texture to produce new hybrid streams that can have very different properties to the original material. This includes differences in characteristics such as mineralogy, deleterious phases, particle size distribution and hardness in addition to economic grade. Material can be conditioned using different breakage energies and intensities to enhance or suppress coarse liberation.

The ability to deliver feed material that has already undergone significant coarse liberation and modification prior to traditional processing plants, enables significant changes to current circuit design and operation.

The objective is to develop sophisticated coarse liberation models and operating protocols which can be used as inputs into next generation circuit design and simulation. This includes design of new coarse separation circuits in the dig and deliver interface as well as modifications to existing circuits. The ultimate aim is to improve efficiency and productivity across a range of operating metrics such as energy intensity and water consumption in addition to net value.

  • Maximising system-value

    While Grade Engineering provides new value based options for manipulating insitu grade and delivering improved productivity, it can also be perceived as creating increased complexity. A high level of user defined options and dynamic scenarios challenges current practice.

  • Implementation at mine sites

    CRC ORE, through its collaborative partnerships, undertakes testing at mine sites around the world as the platform for its research and development.

    These studies continue to expand, as they provide the ideal environment for industry, research and commercial partners to develop and validate step change technologies.

    Projects such as these are only possible through a large scale collaborative effort, and this structure ensures the developed technologies are shaped and validated by operating mine sites and commercial providers in a way that directly addresses the industry’s requirements.
