Prof Godfrey Dzinomwa

Biography

Godfrey holds a B.Sc (Hon) Engineering degree in Metallurgy from the University of Zimbabwe, a PhD in Minerals Process from the University of Queensland in Australia, and a Postgraduate Certificate in Development Economics from the Renmin University of China as well as various leadership courses. He has spent over three decades in the mineral industry focusing on production operations, research consultancy and academia. In the corporate world, he rose through the ranks from engineering through senior management roles to Chief Executive Officer of a number of national and international companies, including one that was triple listed on the Zimbabwe, Johannesburg and London Stock Exchanges. He led various expansion and modernisation projects for those companies. In academia, Godfrey has lectured and led research at the University of Zimbabwe, and was the founding HOD in the Mining Engineering Department at the then Polytechnic of Namibia, which he joined in 2009 to 2011. Since then, he has been involved with the Department on a part-time basis, until 2019 when he joined the Department of Mining and Process Engineering at the renamed Namibia University of Science and Technology on a fulltime basis as the Professor of Extractive Metallurgy. Godfrey has lectured and supervised at both underground and postgraduate levels, with research interests and over 60 peer reviewed publications and over 40 technical reports mainly on mineral education, mineral beneficiation and further value addition.
