ALUMINA QUALITY - USER PERSPECTIVE

Syltevik, D., Lillebuen, B. and Larsen, J.A.

Alumina quality is discussed based on analytical certificates and achieved smelter perfornance. Different technologies have different preferences and limitations with respect to alumina. Performance of a potline depends on alumina quality. Significant losses are associated with some alumina cargos. The major complaint from users is dusting in handling and processing. A high fines content will increase the tendency of segregation and uneven flow behaviour may occur.
