Iron is formed without an extensive release of CO2 in a process compatible with the predominant naturally occurring iron oxide ore, hematite, Fe2O3. Iron is an effective cathode media, and nickel and iridium are effective anodes in the electrolytic formation of iron in molten carbonates, and each can sustain current densities of 1 A cm-2.

Extraction and uses of aluminium. Note You may find all sorts of other formulae given for the product from this reaction.These range from NaAlO 2 (which is a dehydrated form of the one in the equation) to Na 3 Al(OH) 6 (which is a different product altogether).. What you actually get will depend on things like the temperature and the concentration of the sodium hydroxide solution.

To extract iron from an iron ore (common ores include magnetite, hematite, goethite, limonite and siderite) the ore is crushed, powdered, then a reduction reaction with carbon is used. Iron-oxygen bonds are strong, so an even stronger elemental bond with carbon must be presented to the oxygen so that it switches, releasing the iron.
