Alfred Septian 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 and Geotechnical) in December 2016 before commencing his MPhil candidature in 2018 as part of CRC ORE’s Program 3: Extract.

Alfred’s research investigates using the characteristics of surface breakage of ores as a new learning concept to increase feed upgrade. This project has the potential to deliver significant benefits in improving the economic and environmental sustainability of mineral comminution processing.

Upon completion of his MPhil, Alfred hopes to apply his knowledge in the field with a focus on site implementation as a career. He also hopes to continue his journey towards a PHD.

     

Focus area:

Promoting selective breakage using various forms of abrasion techniques.

 

 

This project examines the selective breakage of some ore types. It will require the application of well controlled abrasion techniques.This includes ore texture analysis using microscopic tools to determine the percentage of metal content between the fine and coarse gangue material.

Alfred’s research concentrates on use of the tumbling and planetary mill. This is a relatively common tool to develop abrasion with various particle sizes. The project looks at modifications to optimise the mill. His study will combine the effect of these modifications plus speed and time to reject coarse waste particles while concentrating the valuable mineral prior to energy intensive milling.

This CRC ORE funded work applies this system to reduce energy consumption, increase feed grade and minimise the environmental impact of mining.
