Rubin van Schalkwyk

BTech: Chemical Engineering (CPUT)

Rubin joined CMR-MPTech in 2010 as a Laboratory assistant. During this period he has been involve a numerous comminution plant surveys and a flotation plant survey. He has also been part of a team, who surveyed a comminution circuit as part of the AMIRA P9 project. In 2012 he was permanently appointed as a Research Assistant in CMR-MPTech. During this period Rubin continued assisting in comminution plant surveys, with more responsibility in regards to handling sampling processing of concentrator survey samples. This led to training of ore characterization techniques at Anglo American Technical Solutions. He currently supervises the size analysis (wet, dry and ultra-fine) within the centre. From 2014 till present he is appointed as Scientific Officer and started focussing in stirred milling area. During the AGDP campaign he was selected to lead a team of metallurgists and conduct pilot plant stirred milling test work followed by flotation under the guidance of the Chief Research Officer.

His survey assisting experience covers platinum ores bodies and a gold ore body. His stirred milling experience covers platinum, copper, pyrite, magnetite, manganese ore bodies.
He is responsible for the large comminution rig area within the CMR laboratories, as well as training of new interns and post graduates in this area. He also guide’s ore preparations, test work support, sample processing and data analysis.
