After graduation, Andre worked at Anglo Platinum for a few years as a plant metallurgist on their concentrators in Rustenburg. In 1997 he was appointed as a senior technical officer involved with undergraduate practical training of metallurgists in the Western Cape. In 2002, he joined MPTech, the technology transfer unit within the Centre for Minerals Research. In addition to research projects in the area of comminution, he was involved in numerous on-site process improvement projects in the areas of comminution and flotation. He became MPTech manager in 2016. In this role, Andre is co-ordinating commercial technology transfer projects in terms of industrial training programmes, on-site surveys, process optimization and design projects within the CMR.
