The Journey from Bauxite to Aluminum
Bauxite, the raw material of aluminum, undergoes a complex refining process to become the versatile metal we know. This process begins with the milling of bauxite, followed by a purification technique called the Bayer process.
During the Bayer process, sodium hydroxide reacts with the aluminum oxide from the bauxite, leaving behind impurities. The resulting solution is then evaporated to form a hydrate of aluminum oxide, also known as alumina.
The alumina is further refined in the Hall-Héroult process, where it is melted with cryolite at extremely high temperatures and subjected to an electric current. This electrolysis reduces the aluminum oxide to molten aluminum, which is then refined and cast into ingots.
- From this point, the aluminum can be further processed into various alloys or products for a wide range of applications. | After refining, the aluminum can be formed into diverse alloys or products serving numerous purposes. The refined aluminum serves as a base material for crafting various alloys and products across different industries.
