Aluminium is the most profuse metallic part in the earths crust. 1. 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 processing History, Mining, Refining, & Facts

Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth’s crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to increase
