International conference delegates
International delegates attending the International Conference on the Right to Development hosted on the Bloemfontein Campus.

The International Conference on the Right to Development was held in Bloemfontein for the first time from 25 to 27 September 2019, hosted by the Free State Centre for Human Rights at the University of the Free State. This is the third in the international conference series launched in 2017 with the aim of advancing the right to development both in Africa and internationally. This year’s conference follows the previous two that were held at the Centre for Human Rights, University of Pretoria, in September 2017 and August 2018.  

Based on the theme, ‘The right to development and natural resource ownership’, the 3rd International Conference on the Right to Development offered the forum and opportunity to participants from a diversity of backgrounds and disciplines to interact and share knowledge on their research outputs, which extensively explored questions on how natural resource ownership could contribute to the realisation of the right to development. The keynote address was delivered by Prof John C Mubangizi, Dean of the Faculty of Law at the University of the Free State. 

The three-day conference registered a total of 35 participants and 27 presentations out of the 33 that were scheduled. Participants came from different countries, including South Africa, Botswana, Zimbabwe, the Democratic Republic of the Congo, Cameroon, Nigeria, Ghana, Kenya, Uganda, Ethiopia, and the United Kingdom. Some of those who were unable to attend had the opportunity to present their papers through Skype. The presentations stimulated exciting and robust debates. 

The International Conference Series on the Right to Development is jointly organised and co-sponsored by the Centre for Human Rights, University of Pretoria; the Thabo Mbeki African Leadership Institute, University of South Africa; and the Free State Centre for Human Rights, University of the Free Sate. In its three years of existence, it has progressively established a steady track record of publications, including journal articles in special editions of selected journals and collections of chapters in edited volumes. 

The next (fourth) conference is intended to be much bigger and is scheduled to take place in Kigali, Rwanda, in 2021.

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.
