The lightest of metals
The primary aluminium production industry extracts metallic aluminium from minerals by supplying a large amount of electrical energy in batteries of electrolysis cells where molten metal is separated. Afterwards aluminium is reprocessed by different factories, which use several type of furnaces for the production of aluminium products or semi-finished products. It is in these remelting stages that modern refractory products are mainly used, while the primary aluminium production relies on refractory bricks.
