Joalet Steenkamp Joalet Steenkamp (44) joined Mintek in 2014 after completing her PhD studies. Prior to that, she had 12 years’ experience in industry – operations, projects, and research environments (steelmaking, ilmenite roasting and smelting, and manganese ferro-alloy production) – and 3 years’ experience in academia where she taught courses in pyrometallurgy on both undergraduate and postgraduate level.

Joalet’s main research interests are furnace tapping and production of manganese ferro-alloys. She mainly conducts industrial research for which she was recognised by professional bodies both locally and abroad.

Joalet holds B.Eng., B.Eng.Hons., M.Eng., and Ph.D. degrees in Metallurgical Engineering, all conferred by the University of Pretoria in South Africa. She is a Fellow of the Southern African Institute of Mining and Metallurgy (SAIMM) where she was the founder of the series of Schools on Production of Manganese Ferro-alloys and the series of Conferences on Furnace Tapping. Joalet is also a member of The Minerals, Metals & Materials Society (TMS) and a registered professional engineer (Pr.Eng.) with the Engineering Council of South Africa (ECSA). The South African National Research Foundation (NRF) rated her in 2017 as an ‘Established Researcher'.

Joalet is married and blessed with two children. Her hobbies include photography – her furnace photography received international recognition [1] –, reading, gardening, hiking, and travelling.
