  Recovery of valuable materials from aluminium salt cakes

  200991 · Recovery of oxide aluminium compounds. Davies et al. (2008) studied the treatment of salt cakes by Bayer-type leaching and found that about 43% of the total aluminium present was dissolved in a typical two-stage process with a leach at 100 °C in the first stage and 140 °C in the second stage. Evidently, much of the aluminium is present as ...
