Emerging leaders from across Africa are in Queensland for an Australia Awards Short Course to help them tackle the challenges of social and environmental sustainability and leverage economic development from small-scale mining.
University of Queensland researchers have produced a range of educational resources aimed at tackling safety risks for workers in the gemstone industry.
The University of Queensland and Newcrest Mining Ltd have agreed a new research initiative which provides funding for eight new PhD research projects to develop interconnected and systems-based solutions for a sustainable mining future.
Assessment of comminution energy intensity has traditionally been confined to the crusher and mill motor power consumption. However, a measure of ancillary equipment power consumption is required to fairly compare disparate equipment types and circuit configurations.

Female sapphire miners in Madagascar are among the nation’s hardest workers and poorest people, but their future is looking brighter, thanks to University of Queensland research.
Assessment of comminution energy intensity has traditionally been confined to the crusher and mill motor power consumption. However, a measure of the embodied energy consumed through media wear is required to compare disparate equipment types and circuit configurations fairly.
The comminution energy consumed for an ore can be dependent on the liberation and grade characteristics, therefore different commodities can have inherent energy signatures. The Energy Curve approach can be used to compare comminution energy consumption both within and between commodity classes.
The Comminution Energy Curves contain data from comminution circuits that process a wide range of commodities. Energy per copper equivalent production is used to bring the data together on a consistent basis, but this measure is highly dependent on the chosen comparable metal prices.
