Kyanite and Related Minerals Reserves by Country

India's reserve estimate jumped in 2025 after years of little change, while China's 2023 entry turned a one-country series into a two-country table. The figures come from the USGS Mineral Commodity Summaries 2019-2026 and represent estimated quantities that can be economically extracted. Listed reserves totaled 14,100,000 metric tons in 2025.

India holds 9,100,000 metric tons against China's 5,000,000. Together, the two countries account for the entire listed total, with India holding 64.5% and China 35.5%. USGS marks the world total as XX (not applicable), so no numerical global total is published for this series.

India's share rose from 59.0% to 64.5% in a single year.

India breaks a seven-year plateau

India reported 7,190,000 metric tons in 2018 and 2019, followed by 7,200,000 each year from 2020 through 2024. The estimate then rose to 9,100,000 in 2025, an increase of 1,900,000 metric tons (+26.4%). No other country in the table changed its reported reserve figure in 2025.

China turns the series into a two-country table

China first appears in 2023 with 5,000,000 metric tons and has reported the same figure in both 2024 and 2025. Its addition created a second reserve holder, with China accounting for 35.5% of the listed 2025 total.

Methodology

Figures come from the USGS Mineral Commodity Summaries 2019-2026, with 2025 values estimated. Units are metric tons, as reported. Empty means the source reported no value; 0 means the source reports zero. The source marks the world total as XX (not applicable), so shares are computed against the listed countries. Reserves and production are different measures and should not be combined without equalizing units.
