High-profile positions at National Treasury, the World Bank and now also the International Monetary Fund in Washington, mark an illustrious career for UFS Economics alumna, Vuyelwa Vumendlini.

“Go in full force, hands and feet, and accept this opportunity of a lifetime. You won’t regret it.” These words of Dr Minette Smit, her thesis supervisor, proved to be pivotal advice to a young Vuyelwa Vumendlini. At the time, she was doing her BCom Honours in Economics (1996-1999) and was presented with a scholarship opportunity to complete her master’s degree in the USA.

“I was afraid to leave my home and my comfort zone,” she explains. “But looking back, I’m extremely grateful to have taken that step.”

Her studies culminated in an appointment as Senior Adviser to the Executive Director at the World Bank, then Deputy Director-General: International and Regional Economic Policy at the National Treasury, and now as Alternate Executive Director at the International Monetary Fund (IMF) in Washington DC. As an IMF executive board member, Vumendlini represents 23 English-speaking African countries that are members of a constituency. The Executive Board of the IMF has 24 chairs, representing 24 constituencies from its 189 countries’ membership. Among her duties are considering policy issues and surveillance reports, as well as approving and monitoring IMF programmes involving lending and/or technical assistance.

Since this is the second stint in Washington for her and her children, Simphiwe, Enhle, and Anele, settling down was much easier. “Because of the COVID-19 isolation, we were kind of used to being alone at home, so we didn’t find the solitude that bad while we were still making new friends.”

She misses South African food the most – things like biltong and boerewors – and the proximity of favourite restaurants like Ocean Basket and Mugg & Bean. She has fond memories of her study years, working as an assistant in the Department of Economics, hanging out at Mooimeisiesfontein on Saturdays, and building rag floats for Vergeet-My-Nie and Kestell residences. Plans for the future include tackling her PhD in Economics.

Her advice to UFS students: “Be up to date with what is happening around you. Do not be afraid to do things differently. Be agile in your approach to achieving your career aspirations and be ready to take on those opportunities when they present themselves.”

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
