I hold a Ph.D. in mineral processing and I have more than 13 years industrial and academic experience. My goal is to learn how to implement fundamental understandings in my research for offering solutions to minerals industry and also educate engineers and researchers with problem solving skills for tackling future challenges of our industry.

Planning and implementing multi-disciplinary projects in comminution, flotation and thickening for numbers of funded industrial project provided me with a strong desire to conduct applied research underpinned by sound fundamental understanding. Having opportunity of being in a high calibre research team in the JKMRC, a world leading research centre in mineral processing, and actively collaborating with the international community of researchers has broadened my vision on issues associated with minerals industry. In light of that vision, I have focused my research on a new approach in ore characterisation for comminution which is a crucial step in the path way toward developing mechanistic breakage models. However, I am still continuing the research I did in my Ph.D. to develop a predictive liner wear model.

The joy I experienced as a superintendent engineer in a coal processing plant always keeps me motivated to conduct industry based projects. Coordinating and conducting a couple of successful industrial surveys in Iran and Australia's most recognised mine sites, is due to my passion for being on mine sites and be involved in real world issues. Working with large processing plants which have a high level of safety standards made me an expert in the assessment of safety and risks of conducting industry-based research. Leading a large group of researchers and students and collaborating with site personnel is another invaluable skill I learned while conducting site work. I enjoy presenting my research outcomes to the international research community and discussing the future challenges of mineral processing. I have a great honour of being in the JKMRC which offers a sustainable process for the minerals industry.

Research Interests

  • Mill liner design and wear modelling
    An integrated approach in mill liner design and management to enhance the grinding efficiency through collaboration between operations, liner suppliers, and relining crew
  • Mechanistic approach in liner wear modelling
    Incorporating factors affecting liner wear in the structure of a mechanistic wear model
  • Study surface breakage of rock particles
    Measuring surface breakage of rocks under different loading mechanisms to inform mechanistic breakage models
  • Dynamic modelling for process control and optimisation
    New approach in implementing dynamic modelling of mineral processing circuits for developing process control strategies and accessing process performance

Research Impacts

I have a successful background in industry-based work which enables me to speak with industry in a practical sense. Therefore, my connections with industry have grown substantially in the past few years. This enables me to become a self-sustainable researcher for funding my basic research. I received a good response from industry regarding the "Mill internal design and management" project and I was able to acquire funding from industry and university through applying for competitive grants.

My background and publications in different areas of mineral processing such as comminution, dewatering, coal processing and flotation are recognised by universities, conferences, and journals and I have been asked for examining thesis for different universities internationally, and reviewing journal articles and conference papers in all of these areas.

Working in JKMRC introduced me to a wider research community and offered me opportunities of working with more mine sites, suppliers and engineering companies which make me feel satisfied as an applied researcher.
