Sri Lanka is known for different kind of iron-ore deposits in the Precambrian basement. Among them, hydrated iron ores are predominant in the southwest region.
and iron compounds containing 53.21% TiO2 and 42.57% iron oxides [1,24], Sri Lanka is not entirely benefited from the ore due to the lack of a proper ilmenite processing plant to extract TiO2 and other related compounds in the country itself. In general, ilmenite is globally recognized as a vital resource of both titanium and iron.
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 …
