What happens is (1), workmen extract the substances from the bauxite (10), by grinding (11) the bauxite and putting (12) it into pressure (13) tanks. The mas that remains is filtered (15?, 16) and (1) it forms a liquid (17). After all the processes (18?) it yields (19) a powdery(20)-white (21) chemical called alumina (22). The workmen seperate the aluminum from the oxygen (26) by electricity (27)
