Luleå Conference in Minerals Engineering 2012
From 7th to 8th of February 2012 the annual Conference in Minerals Engineering was held in Luleå, organised by the Mineral Processing group at Sweden’s northernmost University of Technology (LTU). The interest in this event was, as in the previous years, very lively. 85 delegates coming from nine different European countries but also from outside Europe met during the coldest days of the year in the Luleå city hall assembly room where normally the municipal council is in session.
After welcoming the delegates the convenor of the conference, Professor Jan Rosenkranz, gave a short overview on new projects and developments in mineral processing at LTU. The introduction was complemented by information on LTU’s minerals engineering education from Docent Bertil Pålsson and a talk on recent Nordic and European research initiatives by Pär Weihed, professor in ore geology at LTU.
This year’s plenary talk was given by Hakan Benzer, professor at the Mining Engineering Department of Hacettepe University in Ankara, Turkey. In a comprehensive overview he highlighted the development of high pressure grinding technology and described recent advances in defining compressed bed breakage tests for process modelling and design of in particular high pressure grinding rolls.
The further technical programme covered recent research work and developments within academia and industry. Several contributions dealt with the development of new mines in northern Sweden, as for the iron ore deposits in Svappavaara and Kaunisvaara, or the gold-telluride deposit at the Kankberg mine in the Skellefte district. In addition investigations on the extraction of both phosphorous and rare earth oxide bearing minerals from the concentrator tailings in Kiruna and geometallurgical studies for the Kiruna mine and an Ulster gold deposit were presented.
Contributions in the field of mineral processing technology focussed on separation processes, for instance the development of an efficient and environmentally acceptable flotation process for reducing the silica content in the concentrate from the Sydvaranger iron ore, and on comminution processes, among others the design of an ore grinding circuit, incorporating autogenous grinding mills and vertical stirred media mills. In another session results were reported from process modelling and simulation of crushing circuits and from the particle-based simulation of coal agglomeration by stamping.
The conference dinner on the first evening took place at Luleå’s arts centre, combining a festive meal and Swedish dryckesvisor with a wonderful view of the frozen northern harbour. The conference proceedings 2012 are re-edited at the moment and will soon become available on a conference cd (firstname.lastname@example.org).
Welcome back to Luleå on the 5th and 6th of February 2013!
