:: IMPC Lifetime Achievement Award to Prof. Roe-Hoan Yoon

 

The IMPC Lifetime Achievement Award (LAA) "recognises a lifetime of distinguished achievement and outstanding contribution to the advancement of the art, science and industrial practice of mineral processing together with participation in and contribution to the IMPC".

At the IMPC Gala Dinner in Santiago the LAA was awarded to Prof. Roe-Hoan Yoon, a University Distinguished Professor at Virginia Tech. He earned his B.S. degree from Seoul National University (1967) and his M.S. (1971) and Ph.D. (1977) degrees from McGill University. He worked as a Research Scientist at the Canada Center for Minerals and Energy Technology (CANMET) from 1976 to1978 and joined the faculty of Virginia Tech in 1979. He currently serves as Director of the Center for Advanced Separation Technologies (CAST).

Early in his career, his research focused on fine particle flotation, which led to the development of the Microcell flotation columns that are widely used in industry today, and also on the electrochemistry of sulfide mineral flotation. During the last 25 years, Prof. Yoon has been focusing on the study of hydrophobic interactions, which have led to the development of new collectors, dewatering aids, a first-principle flotation model, and new separation processes. More recently, his research group developed a new instrument for visualizing bubble-particle interactions with a nanoscale resolution, which is useful for studying both the hydrodynamic and surface forces affecting flotation. His flotation model can be used to design a flotation circuit on the basis of information on mineral liberation, flotation cell hydrodynamics, and the reagents used. These research activities have resulted in over 330 technical publications, 13 book chapters, 1 book, more than 40 plenary and keynote papers at national and international meetings, and a number of Congressional testimonies. He has advised 40 Ph.D. students, 36 M.S. students, and around 40 post-doctoral fellows and visiting scholars. To date he has more than 70 U.S. and international patents to his credit, many of which have been commercialized through license agreements. He is a member of the National Academy of Engineering (NAE) and has won numerous awards, including the prestigious Gaudin (2003) and Richards (2007) awards.
