Iron Working Processes


All iron ores benefit from processing, which may include washing, roasting and crushing. Roasting was most important since it broke down compounds and caused microcracking in the ore lumps. This facilitated reduction in the furnace, by allowing the reducing gases to penetrate the ore lumps. It was essential that the ore charged to the furnace was as rich as possible.
