It is 103 years since froth flotation was patented, and it is often said to be the 20th century's most important technological development.

It is still the most intensively researched area of mineral processing, as is evidenced by the response to the call for papers for Flotation '09, MEI's 3rd flotation conference, which will be held in Cape Town in November.

Anyone with an interest in flotation should try to be there. So far 10 major sponsors have weighed in with their support and a high-calibre international technical programme for the 4-days has now been published.

The first two days will be devoted to fundamental physics and chemistry, with Prof. Cyril O'Connor, Chairman of the IMPC, and Dean of Engineering at University of Cape Town, presenting a keynote lecture: The effect of the multiple interactions between reagents and mineral particles on flotation performance – a review.

The final two days will deal with applications and plant practice, with Prof. Graeme Jameson, Laureate Professor at the University of Newcastle, Australia, presenting the keynote: New directions in flotation machine design.

There will also be plenty of time for networking, at the beautiful Vineyard Hotel, nestling under Table Mountain, and at the conference dinner at the Spier Wine Estate in Stellenbosch.

Registration forms are now available on the conference website- and it is not too late to submit an abstract. Final papers will be published in a special froth flotation issue of Minerals Engineering.

About MEI:

Minerals Engineering International (MEI) is the largest source of information on minerals processing and extractive metallurgy on the net. The role of MEI is to disseminate information to the mineral processing community via:

  • The Internet. MEI Online was launched in January 1999, to provide a central source of information for minerals engineers around the world.
  • High quality international conferences. Since their inception in 1991, Minerals Engineering Conferences have developed a reputation for bringing together groups of high profile academics, researchers and industrialists, to discuss the latest developments in mineral processing and extractive metallurgy. MEI's policy in organising these events has been to seek the collaboration of internationally recognised Centres of Excellence.
  • Minerals Engineering. This internationally recognised, peer-reviewed journal is published by Elsevier Science, and edited by Dr. Barry Wills of MEI. Each monthly issue contains papers from leading researchers in the field.
