BEFORE the development of the blast furnace, iron smelting was achieved by ore reduction at temperatures below the melting point of the metal, forming an agglomerated 'bloom' of low-carbon iron and slag. The forced-draught (bellows-operated) shaft furnace known from archaeological studies is usually regarded as the pinnacle of this early smelting technology1-3. …

use of iron ore in Sri Lanka. This evidence suggests that iron ore was used in the lithic societies for ritualistic or funerary purposes even before identification of the metallurgical value of iron …

The iron content is high, but considerable amount of copper (in the form of Chalcopyrite) is also associated in this magnetite ore. Therefore, the direct smelling process cannot be used to extract iron from this ore. In Sri Lanka there are no iron extraction industries from iron ore. There are few companies producing iron and steel from scrap iron.
