However, aluminum also has one of the most energy-intensive methods of production owing to alumina’s high melting point of 2,632ºF (aluminum itself has a melting point of 1,220ºF). It is extracted from bauxite ore by dissolving the ore in sodium hydroxide to form sodium aluminate. This is treated with carbon dioxide to form aluminum hydroxide and then heated to make alumina (aluminum oxide), which is reduced to aluminum by electrolysis. Aluminum is a product of countries where electricity is available cheaply, for instance from hydropower sources. It was first isolated in 1825, and therefore has a relatively short history: ...
