Most of the data for phosphate rock production quoted so far comes from the USGS mineral commodity summary publications. So why don't we go directly to the USGS publications instead?
I will add a hypothetical "Years of Reserves Remaining" column based on (Reserves)/(Mine Production Estimated Year). I'm not going to include all the countries.
2021 Publication under Phosphate Rocks:
Country | Mine Production 2019 | Mine Production 2020 Estimated | Reserves | Years of Reserves Remaining |
United States | 23,300 | 24,000 | 1,000,000 | 41.6 |
China | 95,000 | 90,000 | 3,200,000 | 35.5 |
India | 1,480 | 1,500 | 46,000 | 30.6 |
Morocco and Western Sahara | 35,500 | 37,000 | 50,000,000 | 1,351.1 |
Russia | 13,100 | 13,000 | 600,000 | 46.15 |
World total (rounded) | 227,000 | 223,000 | 71,000,000 | 318.3 |
2020 Publication under Phosphate Rocks:
Country | Mine Production 2018 | Mine Production 2019 Estimated | Reserves | Years of Reserves Remaining |
United States | 25,800 | 23,000 | 1,000,000 | 43.4 |
China | 120,000 | 110,000 | 3,200,000 | 29.0 |
India | 1,600 | 1,600 | 46,000 | 28.7 |
Morocco and Western Sahara | 34,800 | 36,000 | 50,000,000 | 1,388.8 |
Russia | 14,000 | 14,000 | 600,000 | 42.8 |
World total (rounded) | 249,000 | 240,000 | 69,000,000 | 287.5 |
