How is wrought iron prepared from cast iron?

Wrought iron is prepared from cast iron by oxidizing impurities in a reverberatory furnace lined with haematite. This haematite oxidizes carbon to carbon monoxide. Fe 2O 3+3C Wrought Iron2Fe+3CO. Limestone is added as flux and sulphur, silicon and phosphorous are oxidized and removed. Hence pure iron called wrought iron is produced.

Metallurgy of Iron

consists of the thermal treatment given to minerals or ores to recover the metal. The process involves chemical reactions at elevated temperature. • The process of extraction of iron is fundamentally very simple as it consists essentially of the reduction of iron oxide by carbon. But as molten iron
