Bauxite - Wikipedia
Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries. Increased aluminium recycling, which has the advantage of lowering the cost in electric power in producing aluminium, will considerably extend the worlds bauxite reserves.
Aluminum processing - Ores | Britannica
Aluminum processing - Aluminum processing - Ores: Aluminum is the third most abundant element on Earth’s surface. Only oxygen and silicon are more common. Earth’s crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form. Its compounds, however, are an …

US Iron and Aluminum Mining During WW2 | Math …
This comment made me curious about mining during WW2. Because metals were so important to the war effort during WW2, I thought it would be interesting to look at how the war affected iron and aluminum mining. Since I have often heard people say that WW2 pulled the US out of the Great Depression, this data may help illustrate what really happened.
