Preliminary geochemical investigations for bauxite in Sri Lanka show the existence of laterite deposits containing bauxitic material approaching the lower limit of commercial grade. The geochemical processes responsible have followed two paths resulting in the formation of lateritic bauxite and lateritic iron ore. While the few samples analysed do not give any information regarding the possible reserves of commercial grade bauxite, the existence of economically important bauxitic material, particularly in the Highlands of Sri Lanka has been confirmed.

Abstract


Preliminary geochemical investigations for bauxite in Sri Lanka show the existence of laterite deposits containing bauxitic material approaching the lower limit of commercial grade. The geochemical processes responsible have followed two paths resulting in the formation of lateritic bauxite and lateritic iron ore. While the few samples analysed do not give any information regarding the possible reserves of commercial grade bauxite, the existence of economically important bauxitic material, particularly in the Highlands of Sri Lanka has been confirmed.
