Iron Making Technology A thousand years before the age of empires in Rome and Greece‚ the Iron Age was ushered into the world with the clank and clatter of the blacksmith’s anvil. The transition from the Bronze Age occurred at different times in different spots on the globe‚ but when and where it did‚ the distinctive dark metal brought with it significant changes to daily life in ancient society‚ from the way people grew crops to the way they fought wars. Iron has remained an essential element

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

Ashland County West Holmes Career Center Mrs. Bender 1 Background Iron powder will react with cupric sulfate in a onetoone ratio (1 mole to 1 mole). The students will also be able to more easily visualize the size of a mole of iron and copper. The result obtained in this lab usually have less than a one percent error. Fe(s) + CuSO4 (aq) > FeSO4(aq) + Cu(s) Iron powder cupric sulfate ferrous sulfate copper In the reaction‚ iron will be the limiting reagent; it will be completely used up in the reaction

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but
