Dr Weiguo Xie

Lecturer in Mineral Processing



Dr. Weiguo Xie is a Lecturer in Mineral Processing at Camborne School of Mines, College of Engineering, Mathematics and Physical Sciences, University of Exeter. He received his BSc (1996) and MSc (1999) in chemical engineering from Tsinghua University, Beijing, China. He has been awarded his PhD in chemical engineering in 2002 at UMIST, Manchester, UK.

His main research interests are mathematical modelling, simulation, optimisation, measurement and control in mineral processing and chemical engineering. He developed an ERT system for on-line measurement and prediction of coalescence in flowing foams. He developed optical fibre chemical sensor-based on-line systems for the monitoring of structural concrete. He has also developed two novel measurement techniques (Piezoelectric Vibration Sensor and Electrical Resistance Tomography) for turbulence in flotation cells. He developed software for non-linear reconstruction of ERT on-line systems, software for optical fibre chemical sensor-based on-line monitoring systems, modelled complex heterogeneous reactions on STAR-CD software, optimisation and advanced MPC (model predictive control) algorithms for large-scale process systems. He has developed an IsaMill model and updated the AG/SAG Mill model and the Ball Mill model.
