Words and meanings to learn
electrolysis
the breaking down of an ionic compound using electricity
bauxite
a sedimentary rock rich in aluminium compounds (such as aluminium oxides and hydroxides); it is the primary ore from which aluminium is extracted
cryolite
a compound added to aluminium oxide to lower its melting point, making the electrolysis process more energy-efficient
aluminium oxide
the compound Al₂O₃ formed from bauxite; it is an ionic substance used as the starting material in the electrolysis extraction of aluminium
ore
a naturally occurring rock or mineral from which a metal can be profitably extracted — such as bauxite for aluminium
