Robson Siphosihle Nkosi's journey is a compelling narrative of resilience, determination, and academic achievement – a story that resonates deeply within the University of the Free State (UFS) community. Born in Mpumalanga and raised under challenging circumstances, Nkosi's path to academic success is a testament to his unwavering spirit.

 

Unwavering determination

His early life was marked by significant loss, having been raised initially by his grandmother, and subsequently by his mother, who tragically passed away just before his final year of high school at Bee Maseko Secondary School, a quintile 1 school in Sheepmoor, Mpumalanga. Facing financial hardship, he relied on the support of friends to complete his matriculation.

Despite these adversities, Nkosi's determination shone through. With the invaluable assistance of his high school teacher, Mokoena Libakiso – whom he now considers his mother – he applied to the UFS to pursue a teaching degree. Although initially accepted, funding delays resulted in his offer being withdrawn. Securing funding later, he enrolled in a BSocSci degree, majoring in Communication Science and Sociology, demonstrating his adaptability and commitment to higher education.

Nkosi’s initial aspiration to switch to a Bachelor of Education degree was redirected by the NSFAS N+1 rule. However, he refocused his goals, setting his sights on a PhD and a career in higher education lecturing. This strategic vision fuelled his academic pursuits.


Leadership. Excellence. PhD.

His leadership skills were honed during his final undergraduate year, serving as the Qwaqwa Campus SRC Deputy President and ISRC Treasurer General. His academic excellence was consistently recognised through academic merit bursaries and the UFS Partial Tuition Fee Bursary, which supported his honours studies. Living in Botshabelo and commuting to Bloemfontein, Nkosi demonstrated his dedication.

During his honours year, he not only excelled as a student, but also as a tutor and Career Ambassador. His academic prowess led to an invitation from his honours lecturer, Yzelle Du Plessis, to facilitate Communication Science classes. He completed his honours degree cum laude, specialising in Leadership Communication.

Nkosi's academic journey continued with a master’s in communication science, funded by the National Research Foundation (NRF). Simultaneously, he gained practical teaching experience as a junior lecturer. He recently completed his master's degree and is now pursuing a PhD in Communication Science, while continuing to teach final-year and honours students on the Bloemfontein Campus.


A life dedicated to education and leadership

His short-term goal is to secure a permanent lecturing position, while his long-term ambition is to become a professor of Communication Science and potentially assume a leadership role in higher education, the public sector, or civil society.

Robson Nkosi's story is a powerful example of resilience, academic excellence, and the transformative impact of education. His dedication and gratitude to those who supported him underscore the importance of community and mentorship. He stands as an inspiration to the UFS community, demonstrating that with determination and perseverance, even the most challenging circumstances can be overcome.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
