The 36th International Course on Process Metallurgy of Aluminium

– Trondheim, Norway, 18 June – 22 June, 2018


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 more than 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.

A special topic this year is A New Low Energy Aluminium Cell with Advanced Digital Platform, CEO of Hydro Aluminium Svein Richard Brandtzæg who also has his Ph.D from this university will be the lecturer.

  • Electrolyte Composition. Background, Common Additives and Typcial Composition
  • Preheat and Start-Up
  • Computer Control of Al-Pots
  • Potline Operation and Pot Resistance Adjustments
  • A New Low Energy Aluminium Cell with Advanced Digital Platform
  • Anodes: The Impact of Raw Material Quality and Anode Manufacturing Parameters on Behaviour in Electrolysis
  • Long Lived Modern Aluminium Cells
  • Cell Voltage and Anode Effect
  • Rectifier Operation During Aluminium Electrolysis

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 18 June, 08:30 and finishing at Lunch time Friday 22 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 airport arrival area every 10 minutes.
