Mineral named after UFS professor
Tredouxite (white) intergrown with bottinoite (light grey), a complex hydrous alteration product. The large host minerals are nickel-rich silicate (grey), maybe willemseite, and the spinel trevorite (dark grey).

More than five thousand minerals have been certified by the International Mineralogical Association(IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classificationwebsite, the Mineralogical Magazine and the European Journal of Mineralogy.

Reitz colleagues start their own company
2014-07-01

The University of the Free State (UFS) and the five colleagues implicated in the Reitz incident of 2008 reached the final chapter in the reparation process in restoring the dignity of these colleagues on Thursday 19 June 2014.

Mr Mothibedi Molete and Mss Mankoe Naomi Phororo, Emmah Koko, Nkgapeng Adams and Sebuasengwe Mittah Ntlatseng, former cleaning staff at the UFS, are now the directors of their own cleaning company, Mamello Trading.

Furthering on its promise to assist the new-found company, the UFS has also appointed Mamello Trading as a service provider responsible for services at its South Campus.

It has been six years since the Reitz incident at the UFS and Dr Choice Makhetha, Vice-Rector: External Relations, described the journey of the past six years as a learning experience for all the stakeholders.

“This journey continues as there is still work to be done, but every milestone achieved, deserves a celebration like today’s,” Dr Makhetha said.

In 2010 the UFS signed a deed of settlement with the colleagues which committed the UFS to help them establish a cleaning company. This was followed by a reconciliation ceremony in 2011.

In 2012 the UFS assisted with the registration of the company Mamello Trading.

Dr Makhetha explained that in 2013 the UFS assisted in training the new directors and mentoring them for 12 months. 

Earlier this year, Mamello Trading signed a cleaning contract of four years with the UFS. Three of the directors’ daughters also received bursaries and are currently studying at the UFS.

Advocate Mohamed Ameermia, Commissioner at the Human Rights Commission, congratulated the management of the UFS on the reparation and reconciliation process they followed in restoring the dignity of the five colleagues.

The directors of Mamello Trading each had a special message of their journey and thanks. Their messages were as follows:

Rebecca Adams – After the video was exposed, I was hurt and was psychologically affected. By offering their apologies to us, the four students indicated that what they had done was a mistake. As a parent, when a child apologises you must accept that apology.
Emma Koko – I was shocked after the video was shown in public. I had a mother-child-like relationship with one of the students and that video tarnished my image as a human being. During the time of reconciliation these students showed remorse for what they had done.
David Molete – I was devastated, hurt and fearful to meet people. I ended up at a psychiatric hospital and attended counseling services which helped me to heal. The students apologised and I accepted because they were sincere.
Mittah Ntlaseng – The video impacted negatively on my dignity. The UFS assisted us with visits to psychologists. Now I feel I am a business owner and it is an opportunity for me to rebuild my self-esteem. 

Naomi Phororo – Mamello Trading is a business venture which is going to bring changes to our lives and families. The training I have received has enabled me to know how to manage the business.
