Personal Profile

Dr. Yahui Zhang joined the Department of Process Engineering at Memorial University of Newfoundland as an assistant professor in mineral processing and hydrometallurgy in January, 2016. Before that, he was a professor in mineral processing and hydrometallurgy at Northeastern University in China. He had worked as a Senior Metallurgist in Beijing General Research Institute of Mining and Metallurgy (BGRIMM) for 9 years.

He earned his first Ph.D. degree in Mineral Processing from the Central South University, Changsha, China, in 1996, and second Ph.D. degree in Materials Engineering from the University of Alberta, Canada, in 2005.

Having been working as a professor in mineral processing and materials engineering for over 10 years, he taught major courses for undergraduate and graduate students in mineral processing, extractive metallurgy and materials engineering, e.g., Hydrometallurgy, Flotation, Research Methodology for Mineral Processing, Mineral Processing Design and Operations, Principles of Chemical Engineering, Solid State Chemistry, Introduction to Materials Science and Engineering, and Engineering Thermodynamics.

He has been principal investigator of more than 20 research projects, and published more than 70 papers in international and Chinese journals (such as Hydrometallurgy, International Journal of Mineral Processing, Minerals Engineering, Chemistry of Materials, Materials Science and Engineering, Mining and Metallurgy, Nonferrous Metals, and Metal Mine) and conference proceedings, and filed 13 patent applications, of which eight have been granted.

With more than 20 years research experience in mineral processing and extractive metallurgy, his research interests lie in the areas of extractive metallurgy of precious and nonferrous metals, mineral flotation, designing and finding of new reagents for flotation and metal extraction, novel processes for waste water treatment, and preparation of nanomaterials and nanopowders by electrochemical methods.
