| Abstract Scope |
The aluminium smelting industry is fortunate in utilising a dominant raw material alumina that performs a range of functions in the process and has proved remarkably flexible in responding to an evolving industry. However the biggest challenge the industry faces is now upon us in the greening of the process in an increasingly carbon constrained world. This presentation will deal particularly with the calcination of alumina, both what we will need of alumina and the prospect of what we can do about the energy footprint of the process. The announcement in June 2021 of Rio Tinto’s study into using hydrogen in alumina refining is but one example of some of the thinking in this direction, following on from an Alcoa initiative in electrically sourced refinery steam. In the calcination process the challenge is also to best understand the alumina product we are likely to require as other innovations are embedded in the smelting process. |
