Web7 de abr. de 2024 · Iron can be obtained by reduction with carbon. Thus, the oxides of highly reactive metals cannot be reduced by carbon. Thus, highly reactive metal cannot be obtained from their oxides by heating them with carbon. Note: The highly reactive metals like potassium, sodium, calcium and aluminium are more reactive than carbon. WebSelf-reduction process: This process is also called auto reduction process or air reduction process. The sulphide ores of less electropositive metals like Hg, Pb, Cu etc. are heated in the air as to convert part of the ore into oxide or sulphate which then reacts with the remaining sulphide ore to give the metal and sulphur dioxide.
