Raoni Lage is a Master of Philosophy (Mphil) student at The University of Queensland’s Julius Kruttschnitt Mineral Research Centre (UQ-JKMRC). He was awarded a Bachelor of Engineering (Mining) in December 2016 before commencing his MPhil candidature in 2017.

Raoni’s project investigates the use of selective and energy efficient mechanisms to further enhance coarse separation and breakage efficiency. The research can potentially deliver important benefits to the industry particularly around improving the economics and sustainability of mining operations.

Upon completion of his MPhil, Raoni hopes to apply his knowledge on test sites. He is looking to continue to collaborate on studies in the area of mineral processing.

     

Focus area:

Enhancing Grade Engineering® by multiple, high speed collisions

 

The focus of Raoni’s research is on the interaction of particles in a controlled energy environment to improve coarse liberation. It utilises a next generation technology known as the Vertical Shaft Impactor (VSI). VSI devices and controlled breakage have been identified as technologies which can potentially improve pre-concentration.

A large component of the costs for a mining operation is the energy used in the comminution process. Early coarse gangue rejection technologies can help limit the quantity of non-valuable feed material being sent to additional stages of processing. This leads to significant cost savings for an operation.

This CRC ORE funded work applies VSI technology as a mechanism to increase feed grades, decrease energy consumption and minimise the environmental impact of mining.
