The 35th International Course on Process Metallurgy of Aluminium

– Trondheim, Norway, 29 May – 2 June, 2017


The course has been given on an annual basis since 1981 (except 2015) and has followed the profound development of the industry. Since 1981 the total attendance has been about 3000 participants from 276 companies, representing 56 countries.

The course provides an updated, comprehensive review of the state of the art of aluminium production. The aim of the course is to “Understand the process and act accordingly”.

The course is aimed at personnel working in the field of commercial aluminium electrolysis at all levels, including technical and project managers, supervisors, potroom engineers, suppliers as well as research metallurgists.

The lecturers are the backbone of the course, and they  have been carefully chosen because of their expertise as well as their ability to communicate. Complete lecture notes will be handed out on arrival Monday morning together with the book “Cathodes in Aluminium Electrolysis” by Morten Sørlie and Harald A. Øye. Instead of the English version a Chinese or Russian version can be obtained.


The Course will be held at Scandic Nidelven Hotel starting on Monday 29 May, 08:30 and finishing at Lunch time Friday 2 June at 12:45 when a chartered bus will bring the participants directly to the airport. Scandic Nidelven Hotel is located near an attractive shopping and restaurant area in downtown Trondheim. It is reached most convenietly from the airport by the Nettbuss (not Værness-Ekspressen) that leaves from the arrival area every 10 minutes.
