Flotation '23 update- the latest keynote and a brand new sponsor

All is developing well for Flotation '23 in Cape Town in November. It will be good to have Prof. Jim Finch and Dr. Glenn Dobby at the conference, the authors of the seminal text Column Flotation. Jim has for many years been MEI's consultant to the conference series, and we are pleased that Glenn will be sharing his views on particle collection in flotation in a keynote lecture.

Glenn will show that some flotation particle collection processes follow the rules of first-order kinetics, coursing bubble recovery in column flotation being a good example. However, particle collection onto gas bubbles in high shear feed slurry aeration machines, such as the Jameson Cell, are not a classic first-order process.

Mechanical flotation machines exhibit coursing bubble recovery, with associated first-order kinetics, in the more quiescent zones. However, the particle collection process in the shear zone of mechanical flotation machines is typically the dominant collection mechanism, and this process is better understood as a probabilistic process and the keynote will review evidence for better understanding particle collection in mechanical cell shear zones, and will suggest a probabilistic approach to modelling.

Dr. Glenn Dobby is co-owner and Senior Consultant for Woodgrove Technologies Inc., Canada, a minerals technology company that develops energy efficient and space efficient flotation systems, as well as advanced process control systems.  From 1991 to 2005 he was co-owner and VP of MinnovEX Technologies Inc., where he was primarily responsible for the direction of technology development in flotation equipment, flotation modelling, comminution modelling and geometallurgy.  Glenn was with Vale Thompson for four years and with MIT for two years before becoming a Professor in the Metallurgy and Materials Science Department at the University of Toronto from 1984 to 1991.

We also welcome a new sponsor to join the other 16 companies already offering corporate support. MetSoP is a team of metallurgists based in South Africa, that offer metallurgical solutions and products. The company specialises in formulating tailor made flotation reagents for various ore types.

Current sponsors

And a reminder that we are now open for abstract submission, the deadline being the end of May. Details of sponsorship and of the exhibition can also be found on the conference website.
