Sri Lanka was the world's leading iron exporter around 3000BC. In 1990, the Samanalawewa archaeological survey identified forty one ancient iron smelting furnaces positioned along the western edge of the foothills and driven by natural draught. These furnaces functioned by heating the air within them thus reducing its density and …
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 ...
