Archaeometallurgical surveys of Sri Lanka have revealed a non-conventional wind-driven iron smelting furnaces for the first time in the world.
Initially, iron ore pellet of size 1 to 2 cms was prepared by subjecting the ore from Ratnapura to a beneficiation process so as to impart porosity and strength. The raw pellets would be subjected to a metallisation process followed by reduction in a mini cupola furnace fabricated in the lab, and the resulting iron would be examined chemically ...
