MEI Online: MEI Conferences: Hydrometallurgy 2000

 

Hydromet 2000

Hilton Hotel, Adelaide, Australia
April 3-5, 2000


Introduction

This 3-day international symposium, organised by Minerals Engineering International in association with the University of Melbourne, Australia was sponsored by the Australian Mineral Research Association (AMIRA).

The conference was held at the Adelaide Hilton, situated in the heart of Adelaide, close to the shopping, theatre, central market and business districts, and close to the famous Barossa and Clare Valley wine regions. Adelaide


Conference Report
Prof. A.E.C. Peres, UFMG, Belo Horizonte, Brazil

Hydromet 2000 was a remarkable conference. The number of delegates (65), representing 13 different countries, was just perfect to guarantee a wide range of subjects being covered without the undesirable side effect of overcrowding. A predominance of academic investigation was observed among the papers presented, but most of the results apply directly or indirectly to industrial practice. An interesting feature was the fairly large number of papers derived from the cooperation between different institutions in the same country or even in different countries.

Hydrometallurgy has always played a relevant role in Minerals Engineering Conferences. However, the idea of holding a conference on this specific topic was excellent. Hydrometallurgy is a subject that proves to be important enough to attract papers on specific sub-areas such as Bio-hydrometallurgy, Gold and Silver Ores, Non-Precious Metal Ores and Environmental, beyond contributions on General Hydrometallurgy.

I had the privilege of attending the first conference of the already long series: "Reagents in Minerals Engineering", held in 1991, at the Camborne School of Mines, Redruth, in the heart of the charming Cornwall area. I always do my best to attend the Minerals Engineering Conferences for several reasons. From the first conference at an old university auditorium to meetings held in first class hotels all over the world, several features have been preserved: excellent organisation, friendly atmosphere, first class papers, publication in an indexed international journal after peer review and acceptance, profitable discussions between people from different countries, institutions and backgrounds. The overall atmosphere of the conferences organised by Minerals Engineering International enhances the possibility of what I define as "Lounge Engineering". Several technological improvements started from an informal exchange of ideas in conferences lounges.
