The Aluminium shaped by the electrolytic reduction of alumina dissolve in an electrolyte (bath) mainly contain cryolite (Na 3 AlF 6) sinks to the bottom of the Cell from where it is collected and sent to a melting or holding furnace, that is used to hold the hot metal and uphold desired temperature for casting.
Aluminum ore (bauxite) must first be mined then chemically refined through the Bayer process to produce an intermediate product, aluminum oxide (alumina). Alumina is then refined through the HallHéroult process into the pure metal by an electrolytic process. Aluminum is 100 percent recyclable without loss of its properties.
