Mercury is a less reactive metal and it can be extracted from its sulphide ore cinnabar by heating it in air alone. 1. It is first heated in the presence of surplus air (roasting process). WitrynaSelf-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.
