Student graduation

May 11 , 2021

A very enthusiastic well done to Lesego Siwela, who graduated from the University of Pretoria last month with her Batchelor of Engineering (metallurgical) degree.

Although it has been an interesting challenge to mentor a student throughout lockdown, she has done admirably. Lesego worked on an incredibly varied set of projects, bouncing from hydrometallurgy (copper and gold recovery and cobalt leaching) to food processing (colour removal from sugar and inversion of glucose syrup) to development of analytical methods for our internal laboratory.
