Versuchsvorschrift

Causticisation with lime slurry then converts the sodium carbonate and bicarbonate to sodium hydroxide. The recovery of sodium hydroxide from the effluent results in soda savings of approximately 0.6 tonne/tonne of sodium oxalate. It is estimated that this will result in savings of over 5600 tonnes per annum at the Worsley Alumina refinery alone.
