Abstract

The dissolution behaviors of primary and secondary alumina in aluminum bath were compared. The dissolution of primary alumina can be divided into a few key steps: fast dissolution upon feeding, crust formation and sludge dissolution. The dissolution rate of secondary alumina is much faster than that of primary alumina. Industrial measurements of alumina concentration in 410 kA and 500 kA cells confirmed the laboratory results
