Home General Introduction Conference Report Conference Programme Published Papers Delegate List Photos Flotation '13  


The 5th International Flotation Conference (Flotation '11) was organized by MEI in consultation with Prof. D. Bradshaw and Professor Jean-Paul ('J-P') Franzidis. It was sponsored by Maelgwyn Mineral Services, FLSmidth, JKTech, SNF Flomin, Outotec, Xstrata Technology, Axis House, Flowrox, FEI, CiDRA Minerals Processing, Cheminova, Senmin, Nalco Africa & SGS Canada. Media sponsors were International Mining and the Gold & Minerals Gazette.

Flotation '11 featured 2 discrete symposia:


November 14-15: 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 focused on:

  • Fundamental reagent and flotation chemistry
  • Bubbles, froths, bubble-particle interactions
  • Flotation cell hydrodynamics, kinetics and scale-up

The keynote lecture "Bubbles, frother and flotation" was given by Prof. James Finch, of McGill University, Canada, and a Fellow of the Royal Society of Canada.

November 16-17: Flotation Applications and Plant Practice

This two day symposium focused on the application of flotation, and included 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 "When are flotation models useful?" was given by Dr. Dan Alexander, CEO of JKTech Pty Ltd, Australia.

"The MEI Flotation conferences now seem to have a firm foothold in the international calendar and the variety of papers [at Flotation 09] was just as good as in 2007."
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
