The 38th International Course on Process Metallurgy of Aluminium

The 38th International Course on Process Metallurgy of Aluminium

Scandic Nidelven Hotel,Trondheim, Norway

June 15 – June 19(20), 2020

The course has been arranged on an annual basis since 1981 and has followed the profound development of the industry. Since 1981 the total attendance has been more than 3000 participants from 280 companies and universities, representing 56 countries.

The course provides an updated, comprehensive review of the state of the art of aluminium production. New Developments are emphasised. 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 aim of the course is to “Understand the process and act accordingly”.
Not only lectures but also Group discussions of actual problems and social arrangements with informal discussions are important parts of the course.


The Course will be held at Scandic Nidelven hotel, Trondheim, Norway and start on Monday June 15, 0830 and finish at lunchtime Friday June 19, 2020 at 1240. A complementary visit to Hydro Aluminium Sunndal  will be arranged on Saturday June 20, 0730 – 1730. Trondheim is reached directly by air from London, Amsterdam, Copenhagen or Oslo. Scandic Nidelven Hotel is located near an attractive shopping and restaurant area in town. The Bus Værnes Ekspressen leaves  from the airport arrival area and stops at Royal Garden hotel about 100m from Scandic Nidelven hotel.
