بيت /how to get aluminum out of bauxite
Bauxite is the world's major source of aluminum. It is a rock solid kind of aluminium ore formed when the strong weather conditions affect the rocks and soil of the mountain. The producers of Bauxite in the world have more mountain ranges. In order to get the heavy rocks broken down into smaller usable chunks, the mountains need to be blasted.

Simply put, Bauxite ore is one of the largest sources of aluminum in the world. In order for the ore to take the form of aluminum, it needs to be processed with help from chemical treatments. Then the resulting alumina will be smelted through an electrolysis process which will create aluminum metal.
