The 8th International Flotation Conference (Flotation '17) is organised by MEI in consultation with Prof. Jim Finch and is sponsored by Axis House, Maelgwyn Mineral Services, FLSmidth, Aminpro, Outotec, Magotteaux, Promet101, Woodgrove Technologies, Kemtec, ZEISS & Solvay. Media sponsors are Mining Prospectus & International Mining.
Flotation '17 features 2 discrete symposia:
November 13-14: Flotation Fundamentals: Physics and Chemistry
Although now over a hundred years old, the fundamental aspects of flotation are still being intensively researched, and new machines developed. This two day symposium will focus on:
- Fundamental reagent and flotation chemistry
- Bubbles, froths, bubble-particle interactions
- Flotation cell hydrodynamics, kinetics and scale-up
The keynote lecture, "Developing a Flotation Model from First Principles", will be given by Prof. Roe-Hoan Yoon of Virginia Tech., USA.
Prof. Yoon is a University Distinguished Professor at Virginia Tech, where he currently serves as Director of the Center for Advanced Separation Technologies.
During the last 27 years, Professor Yoon has been working on hydrophobic interactions, which has led to the development of new flotation promoters, dewatering aids, and a first-principle flotation model. More recently, he has developed the hydrophobic-hydrophilic separation (HHS) process to recover and concomitantly dewater ultrafine particles. As part of his studies on hydrophobic interaction, Dr. Yoon's group has developed a method measuring both hydrodynamic and surface forces in the thin liquid films of water formed between air bubble and mineral surface.
He is a member of the National Academy of Engineering, and has won numerous awards, including the prestigious Gaudin (2003) and Richards (2007) awards from the Society of Mining Engineers and the 2014 Lifetime Achievement Award from the XXVII International Mineral Processing Congress, Santiago, Chile.
November 15-16: Flotation Applications and Plant Practice
This two day symposium focuses on the application of flotation, and will include sessions on:
- Plant Operations, particularly related to new technology, and process mineralogy problems
- Flotation Circuits, and their modelling, simulation, control and optimisation
- Flotation machine developments
- Metallic, non-metallic and coal flotation
- Environmental considerations
The keynote lecture "Existing Opportunities for Increasing Metallurgical and Energy Efficiencies in Concentrators" will be given by Dr. Bill Johnson, Senior Principal Consulting Engineer, Mineralis Consultants Pty Ltd and Adjunct Professor, JKMRC, SMI, University of Queensland, Australia.
Bill Johnson obtained a PhD in mineral processing from the University of Queensland in 1972. After working for ASARCO in Arizona until 1976, he lectured at the University of Melbourne. He joined the CSIRO Division of Mineral Engineering (1978-1982) where research on the Zinc-Lead Concentrator at Mount Isa Mines Limited was his main project. In 1982, he moved to Mount Isa where he continued applied research on the difficult ore treated in the Zinc-Lead Concentrator and other plants and ores of MIM Holdings, becoming the Minerals Processing Research Manager (1989-1997) of the laboratory and pilot plant facilities at the operating site in Mount Isa. Development of a circuit for McArthur River zinc-lead ore recommenced in August 1989 under his direction; this ore had even more difficult properties than the Mount Isa zinc-lead ore, well known for its difficult properties; one important outcome of the McArthur River project was the IsaMill technology.
"Many thanks for yet another outstanding Flotation Conference [Flotation '13]. It is now widely accepted that this series of Conferences are 'must attend' events for both flotation researchers and practitioners. The great value of attending the Conference is that it provides an excellent forum for an exchange of views among those doing more fundamental research and those from industry who are able to share their successes and challenges with the audience. This is why the Conference makes such a valuable contribution to the practice of flotation which, as you reminded us in your opening address, is one of the most important of all industrial processes! I look forward to attending Flotation '15!
Cyril O'Connor, IMPC Chairman
"Congratulations on Flotation 07. It was an excellent meeting."
Prof. Graeme Jameson, University of Newcastle, Australia
"It [Flotation '11] was my first international conference. It was excellent, bringing all the big names whom I thought existed only in print. Definitely looking forward to the next in the series."
Tsepang Khonthu, Uni. of Cape Town, South Africa
"Many thanks for a great conference [Flotation '11], well organised with quality papers. I get the feeling the conference and venue is becoming known not only for good papers but also (and of equal importance) as a very conducive networking site."
Martyn Hay, Eurus Mineral Consultants, South Africa
"This conference [Flotation 07] will go down in the history of flotation as a point of reference when flotation turned a new page and moved on to its next level of knowledge and best practice."
Dr. Norman Lotter, Xstrata Process Technology, Canada
The conference is organised by Minerals Engineering International (MEI) in consultation with Prof. Jim Finch.
Jim has been on staff in the Department of Mining and Materials Engineering, McGill University since 1973, serving as Chair from 1988 to 1991 and was appointed to the Hatch Chair in Mining and Metallurgical Engineering in 2005. He has held a succession of NSERC Chair awards since 1991. He has co-authored over 250 articles and one book and supervised over 80 post-graduate students.
He has received the Gaudin Award from SME, the Alcan Award, Silver Medal, and Falconbridge Innovation Award from MetSoc/CIM, and from NSERC in 2008, as team leader, the Leo Derikx Synergy Award for Innovation. A conference in his honour was held in Sudbury, 2009 and he was elected to the Academy of Science of the Royal Society of Canada in 2002.
