Economies of scale and alumina refining
plant on-line time of an alumina refinery with more than one production unit/train – such as a digestion unit – is higher than a plant with one production unit only due to increased flexibility in equipment operation and maintenance. The effect on plant on-line time is generally limited (indic. 0.2-0.5% abs), however, it may vary
