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.
Extraction of aluminium. Aluminium is the most abundant metal on Earth. Despite this, it is expensive, largely because of the amount of electricity used up in the extraction process. Aluminium ore is called bauxite.The bauxite is purified to yield a white powder, aluminium oxide, from which aluminium can be extracted.The extraction is done by electrolysis. But first the aluminium oxide must be made molten so that electricity can pass through it.luminium is the most abundant metal on Earth. Despite this, it is expensive, largely because of the amount of electricity used up in the extraction process.
