presenceDefined as: The total amount ever mined to date. This could theoretically be seen as a "resource" to eventually recycle.
(tonnes)
Aluminium (Al) 200 [3] : 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.
Chromium (Cr) 41,000,000 560,000,000
Cobalt (Co) Actual labor intensity is probably higher than this, because most cobalt comes from the Congo where wages are much lower than the "$4/hour average wage" used in estimating from mineral prices. : 2,974 190,000 8,300,000 25,000,000
Copper (Cu) 757 [4] : 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
Gold (Au) 4,935,542 3,100 52,000 15,000 discovered + 18,000 undiscovered
Not sure why this is lower than reserves
 : 33,000
Graphite (C) 1,300,000 330,000,000 800,000,000
Iron (Fe) 50 [5]per steel production : 20 1,300,000,000
Lead (Pb) 168 4,500,000 85,000,000 2,000,000,000
Lithium (Li) 5,724 130,000 26,000,000 98,000,000
Nickel (Ni) 2,189 3,300,000 100,000,000 300,000,000
Oil [6] : 5,064,140,000 [6] : 235,838,240,000
PGMs Platinum-group metals (Pt, Pd, Rh, Ir, Ru, Os) based on a 50/50 average of platinum and palladium prices : 3,237,432 400 70,000 100,000
Salt (NaCl) 290,000,000
Sand 380,000,000
Silver (Ag) 58,236 26,000 550,000
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. 6,400,000
Uranium (U) 9,517 [7] : 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.
  1. Estimated from the market prices of minerals (unless otherwise specified) (www.dailymetalprice.com - Feb 17, 2023), using very simplified assumptions: global average wages of $4/hour; wages account for 1/3 of the mineral's market price. These assumptions are far from perfect, so if you know of more accurate data on the labor-intensity of any mineral, please post it in the discussion and we can fit it in the table.
