Willem Rossouw receives scholarship
Willem Rossouw, a postgraduate student in the Department of Process Engineering, has been awarded an Outotec Postgraduate Scholarship by the Western Cape branch of the Southern African Institute of Mining and Metallurgy (SAIMM). This scholarship is awarded to postgraduate students in their first year of study that conduct research focussing on sustainability in mineral processing and extractive metallurgy. Willem’s postgraduate research work forms part of a project aimed at developing a hydrometallurgical process for the recovery of metals from electronic waste; this project is also supported in part by the National Research Foundation of South Africa.
The recovery of metals from electronic waste prior to disposal has become of major environmental and economic interest, as a result of the fast rate of technological development that has led to a decrease in the service life of electronic devices and an increased rate of electronic waste generation. Willem’s project specifically focuses on the selective recovery of base metals by means of acid leaching processes. An important aspect of the project is to evaluate the effects of different physical separation steps employed during the pre-treatment of waste circuit boards on the efficiency of the leaching processes.
