In late April 2017, Prof.Cyril O’Connor and Dr.Jenny Wiese from University of Cape Town (UCT) visited BGRIMM for a ten-day joint research on milling technology and use of electrochemistry in flotation, which is part of work of China-South Africa science & technology cooperation program. During the stay, Prof.O’Connor, together with Dr. Wiese, gave a presentation on “Review of Activities of CMR Reagent Research Group” in a symposium held at BGRIMM R & D Center. Vice president Han Long hosted the symposium which was attended by the research staff from R&D management department, mineral processing division, mineralogy division, and BGRIMM MTC. BGRIMM has maintained a good and long-term cooperative relationship with UCT, and the two sides has jointly conducted two international collaborative research programs since 2012.
