How Cement is Made
The last stage of making cement is the final grinding process. In the cement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. This powder is the final product, cement.

Aluminium production process
At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950℃. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium settling at the bottom of the reduction cell.

The ultimate product of calcination is the most stable phase of alumina, corundum or -alumina. This is, however, not desirable for smelting, because -alumina is slow to dissolve in the bath (refer to Section 24). For the formation of Smelting Grade Alumina (SGA), calcination is carried out at around 950°C.
