General Notes

123 delegates attended Minerals Engineering '98 (see Conference Report below).

The papers from the conference are now being refereed, with a view to publication in Minerals Engineering journal. Current status of publication of the papers will be displayed on this home page.


Conference Report
By C. Magnus Evertsson, Machine & Vehicle Design, Chalmers University of Technology, S-412 96 Gothenburg, Sweden

The 8th Minerals Engineering conference was held in Edinburgh, the historic and beautiful capital of Scotland. As usual the conference was well organised with a carefully chosen venue.

The Minerals Engineering Conferences have had a steadily increasing number of attendants. This year there were over 120 registered delegates. The number of different nationalities is impressive 25 different countries were represented. With participants from Europe, North and South America, Australasia, Asia and Africa the conference was truly international.

The conference was opened by Prof. J.A. Finch, McGill University, Canada, who gave an interesting keynote lecture entitled "Innovations and future trends in flotation cell design". The following technical sessions comprised almost 50 papers. The topics of the technical sessions covered the following areas:

  • Flotation Technology and Practice Process Control
  • Simulation and Optimisation
  • Bio and Hydrometallurgy
  • Gold Metallurgy
  • Gravity
  • Magnetic and Optical Separation
  • Froth Flotation Fundamentals
  • Comminution
Every session was well attended and almost every paper was followed by a couple of questions. Thereby, the authors got instant and high quality feed back of their work. After refereeing the papers will be published in Minerals Engineering.

During and after the technical sessions more than 45 posters were displayed. The posters comprised a wide variety of areas within minerals processing.

After the three intensive days at the conference the delegates had the opportunity to take part in a guided excursion to the Kingdom of Fife. Golfers played at the Jubilee course at St. Andrews, while non golfers visited the 16th century Falkland Palace. The day ended at Glenturret Distillery, where Highland Malt Whisky were tasted.

Next year's Minerals Engineering Conference is to held in Falmouth, Cornwall, England. The meeting is strongly recommended for the reasons already indicated above high quality presentations, well attended sessions, the mix of academic and industrial interests. Another important thing is the social aspects, Minerals Engineering Conferences provide a good opportunity to meet people with similar interests and ideas. We look forward to Minerals Engineering `99!
