Integration of operational strategies and engineering solutions to effect coarse separation in the dig and deliver interface optimised for net value.

This includes advanced blasting design and fragmentation controls; bench scale down hole and top of hole sensors; screening for grade by size conditioned run of mine material; and on-line sensors for coarse material flows at shovel, truck and conveyor belt scales.

The aim is to generate new higher-grade feed streams through physical removal of low value components at coarse (10-1000 mm) particle size distributions after blasting and primary crushing.

The ultimate aim is to undertake coarse separation in-pit as part of dynamic short-term mine planning. This involves design of radical in pit crushing and separation equipment that can also improve digging and loading efficiencies.

  • 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.
