| Aluminium (Al) | [2]: 61 | 69,000,000 | Global resources of bauxite are estimated to be between 55 billion and 75 billion (metric) tons and are sufficient to meet world demand for metal well into the future.... As a general rule, 4 tons of dried bauxite is required to produce 2 tons of alumina, which, in turn, can be used to produce 1 ton of aluminum.16,000,000,000 |
In 2022, aluminum recovered from purchased scrap in the United States was about 3.4 million tons, of which about 56% came from new (manufacturing) scrap and 44% from old scrap (discarded aluminum products). Aluminum recovered from old scrap was equivalent to about 29% of apparent consumption. | |||||||
| Cement | 4,100,000,000 | Cement also has non-energy-related CO2 emissions: 0.81 tonnes CO2 per tonne cement. Also note that concrete is about 15% cement by mass; the rest is sand, rocks, and steel rebar. | |||||||||

| Copper (Cu) | [3]: 12 | 22,000,000 | 890,000,000 | A U.S. Geological Survey study of global copper deposits indicated that, as of 2015, identified resources contained 2.1 billion tons of copper, and undiscovered resources contained an estimated 3.5 billion tons.3,000,000,000 |

| Thorium (Th) | Production and reserves are associated with the recovery of monazite in heavy-mineral-sand deposits. Without demand for the rare earths, monazite likely would not be recovered for its thorium content under current market conditions. |

| Uranium (U) | [5]: 8,070,000 | The energy density of uranium is much higher, at 574699 GJ/tonne for conventional nuclear reactors, and 82099829 GJ/tonne as a theoretical maximum for breeder reactors. Uranium occurs in nature as a mix of two isotopes: U235 (0.7%) and U238 (99.3%). Conventional nuclear reactors can only make use of the U235 component. | |||||||||
