A route to the synthesis of aluminium sulphate from local raw materials
Open Access
|Jun 1983Abstract
The annual requirement of aluminium sulphate in Sri Lanka is about 15,000 metric tons and this is totally imported. Since bauxite is not available in Sri Lanka, Dediyawela ball clay containing about 36% Al2O3 and lateritic clays containing about 20% Al2O3, were used as sources of alumina for the synthesis of aluminium sulphate. Treatment of calcined ball clay with H2SO4 results in the formation of aluminium sulphate. The recyclic process of treatment reduced the free acid content in the product. By recrystallisation the excess iron was removed.
