It is necessary to consider carefully the economy of alumina production due to different chemical and mineralogical properties of aluminum hydroxide. A significant amount of cost can be saved by reducing the number of aluminum hydroxide sample analysis. For this purpose, a linear relationship has been developed between the contents of sodium and, iron oxide in the aluminum hydroxide. The main benefit from such a relationship is to predict the aluminum hydroxide content from rather cheaply obtainable sodium contents. The application of this relationship has been demonstrated for alumina production at Seydisehir Alumina Plant in Turkey.
