This CRC ORE project (P1:007) led by Ron Berry, investigated the application of surface analytical techniques for measuring bulk and particle sorting applications in a Grade Engineering® context. Upgrading mill feed by selectively sorting high-grade material at the bulk scale or on the particle scale requires application of different technological methods. Outcomes of the report identified surface analytical techniques suited to being used for sorting both blasted material (e.g., in shovels) and crushed material on conveyors to improve mill feed grade in low-grade, high-tonnage bulk mining operations. Outputs include a confidential report to CRC ORE sponsors.
