The Global Comminution Collaborative (GCC) led by The University of Queensland (UQ) welcomes its sixth member university. Technische Universität Braunschweig (TUBS), Germany brings expertise in ultra-fine grinding and modelling, and fine particle strength, sizing and analysis to the GCC, which conducts comminution research on mining sites.
Comminution is a process in which solid materials are reduced in size through crushing and grinding to make the contained valuable materials accessible for further processing and extraction.
GCC founder Professor Malcolm Powell, who is based at the Julius Kruttschnitt Mineral Research Centre at UQ’s Sustainable Minerals Institute describes comminution as an important but energy-intensive operation in mineral processing, consuming up to 40 per cent of a mine’s power supply and up to four per cent of the world’s electrical energy.
Professor Powell explains comminution is a discrete area of research but has a strong impact; apparently small site improvements can have considerable flow-on effects in improving efficiencies and reducing costs. GCC’s member universities already bring expertise in many areas of comminution; the addition of TU Braunschweig ensures that the full scope of comminution is covered from coarse feed to finest final product.
TUBS fine grinding leader Professor Arno Kwade commented that the Institute of Particle Technology of the TU Braunschweig has a leading reputation in fine grinding for various processing industries; they now look forward to extending this into the minerals industry, providing innovation through collaboration.
TUBS will join UQ, the University of Cape Town in South Africa, Chalmers University of Technology in Sweden, Hacettepe University in Turkey, and the Laboratory of Mineral Technology at the Federal University of Rio de Janeiro in Brazil in the further development of the academic centre of excellence for comminution. Core research projects that focus on issues common to the industry are researched collaboratively across the six GCC centres of excellence.
