Konuray Demir is a mineral processing engineer with over ten years of experience in commissioning, operation, research, consultancy, and engineering environment. Expertise in coarse particle flotation, vertical roller mills, cyanidation processes and modelling and simulation of mineral processing circuits.

Konuray’s particular interest is in coarse particle flotation at the JKMRC. He is currently working on modelling of HydroFloat® cell as his PhD subject. Additionally, Konuray is investigating different aspects of HydroFloat® such as circuit optimisation, developing ore characterisation methods, etc. as well as other methods targeting coarse particle flotation. Konuray adopted a hands-on approach for his engineering and research works. He has lead/attended numerous site campaigns/surveys for various commodities and implemented alternative solutions by the help of modelling and simulation techniques.

Konuray is a passionate researcher who would like to create a difference that can be applied to industrial plants. In recognition of his research work, Konuray has received several awards: Ian Morley Prize 2019; Prof Ihsan Dogramaci Superior Achievement Award; and 1st Prize Annual Project Symposium Hacettepe University.


After completing an undergraduate degree in Mining Engineering at Hacettepe University in 2010, Konuray joined the Hacettepe Comminution Group (HCG) in Hacettepe TechnoPark. In 2012 he relocated to Germany to work as a research & development engineer at Loesche GmbH. In 2014, and wanting to gain more industrial experience, Konuray started working as Technical Operations Lead in a gold mine in Sudan, where he designed and commissioned a cyanidation plant. Konuray’s ambition in coarse particle recovery and admiration for the JKMRC, brought him to Australia. He started his PhD at JKMRC in 2017. His is currently working on “Empirical Modelling of HydroFloat® Cell” as PhD research.

Industry Engagement

With more than ten years of experience in the mineral processing area (more than eight years actively on site), Konuray has been involved in numerous national and international industrial/research projects. He has worked on industrial projects in Africa (South Africa, Sudan, Ghana), Asia (UAE, Laos), Europe (Germany, Bulgaria, Turkey) and Australia.
