Extraction. Mercury is extracted from cinnabar by a simple process of heating and collecting the vapors. In conventional factories, the rock is ground up into a fine powder, which is then heated.The sulfur in cinnabar reacts with the oxygen in the air forming sulfur dioxide.ercury is extracted from cinnabar by a simple process of heating and collecting the vapors. In conventional factories, the rock is ground up into a fine powder, which is then heated.
ALUMINIUM This page starts by looking at the extraction of aluminium from its ore, bauxite, including some economic and environmental issues. It finishes by looking at some uses of aluminium.Extracting aluminium from bauxite Introduction Aluminium is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic. Instead, it is extracted by electrolysis.The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite-another aluminium compound. The aluminium oxide has too high a melting point to electrolyse on its own.t finishes by looking at some uses of aluminium.
