Dr Ratale Henry Matjie spent 37 years, 11 months at the Global Petro-chemicals and Energy Giant, Sasol Limited and universities (North-West University (NWU) and Vaal University of Technology (VUT), South Africa (SA). He is an expert in renewable energy (biogas, solar, biofuels, etc.). Dr Matjie brings into Morwakoma Matji investment Holdings (Pty) Ltd (“MMIH”) global experience in renewable energy from various sources (i.e., Biomass, Solar, waste to energy, etc.). Dr Matjie’ s research interests have ranged widely from: Froth-flotation of Coals and Ores, Coal Ash Characterizations and Utilizations, Extraction of High-value Inorganic Elements/ Rare Earth Elements from Coal/Biomass ashes, Spent Catalysts, Tailings and Ores by Pyro and Hydrometallurgical methods, Coal Characterizations, Solvent Extraction, Flocculation, Agglomeration, Waste Classification and Management, Coal Combustion, Renewable Energy Projects (Pyrolysis/co-pyrolysis coals, coal fine wastes and biomasses, Liquefaction of Plastic/Tea/Coal Fines/Sewage Sludge Wastes, Torrefaction, Gasification), and S and V chemistry in the Stretford process liquor.
On the academic side, he has obtained two master’s degrees in chemistry from University of the Witwatersrand (Wits), Johannesburg, SA (Title: Selective recovery of metal values from a spent catalyst composition: Distinction) and Vaal University of Technology (Title: Selective removal of iron and titanium from an aluminum containing aqueous phase). Furthermore, he obtained a PhD (Metallurgy) from University of Pretoria (UP) and two post doctorate qualifications from NWU and VUT. In terms of global publications, over the past 10 Years he produced over 124 research outputs (51 Refereed Journal articles +Over 69 conference papers/ presentations/posters + 4 Patents (Production of Inorganic Chemicals from Low Temperature Combusted Coal Ash, South African Patent: 98/583, RSA; Extraction of Metals, South African Patent: 93/3108, 1993, RSA; Selective Recovery of Metal Values from a Spent Catalyst Composition, Pct/Za01/00128, Wo 02/18663 A2. 2002; Selective Recovery of Metal Values from a Spent Catalyst Composition, Za 2003/01671 (Divisional) + 1 Chapter Book (Coal gasification: In Applied coal petrology, pp. 119–44.
