About Us

Alexei Krassnokutski

Alexei Krassnokustski completed his BSc in 2005 at the University of the Witwatersrand. He continued his education by registering for an MSc at Wits in 2006 which he converted to a PhD in 2007. Due to rapid progress of a unique topic, he completed his PhD by the beginning of 2010 and was awarded Sasol’s best post-graduate student award in the process. His work at Roytec Global lead to the development of the Radflow™ feedwell which showed significant performance improvement over traditional thickener technlogy. This has become the Roytec Global standard with an impressive record of feedwell retrofit success stories stretching from the DRC to New Caledonia.
