Additional information
Rock fragmentation is an essential part of mining and mineral separation but consumes vast amounts of energy. Quantum-mechanical simulations and high-resolution STM (scanning tunnelling microscopy) show, for the first time, the relationship between rate of fracture propagation, molecular impurities and the roughness of the fracture surface. This understanding is essential for improving the energy efficiency of particle size reduction. This paper is the culmination of five years of fracture research in the Rio Tinto Centre for Advanced Mineral Recovery at Imperial College. Results of this fundamental work on fracture resulted in the £5.5m Centre renewal to the end of 2018.
