Anode plants for tomorrow's smelters: Key elements for the production of high quality anodes

摘要

Why should smelter management care about anode quality? From considering all the input materials required to produce primary aluminium, those for anode production have the greatest variation of properties relevant to quality. Substandard anodes have a significant impact on the cost of metal production and greenhouse gas (GHG) emissions. Modern smelters typically have annual capacities in the range of 750kt/y - 800kt/y and are designed to double capacity in expansion phases. Such smelters require anode plants with an initial annual output of 500kt/y which has to be doubled if the smelter is expanded to twice its size subsequently.
