EXTRACTING METALS FROM THEIR ORES
Manganese is produced by the reduction of its Oxide with Carbon. • Copper used to be produced this way but nowadays some ores are converted into solutions containing Cu2+ ions. • The copper is extracted by reducing with scrap iron 2MnO (s) C (s) 2MnI (s) CO2 (g) This is "greener" as no CO2 is produced and scrap iron is cheap and …

Iron Extraction by Blast Furnace Metallurgy
The process of extracting iron from its ore involves crushing the ore to a powder and then heating it in a furnace with a carbon source. The carbon reacts with the oxygen in the ore to create carbon dioxide gas, which leaves the furnace through the smokestack. The molten iron is then poured into molds to cool and solidify.
