Mica Reserves by Country (Scrap and Flake)

China first appeared in the series in 2023 with 1,100,000 metric tons, creating a second major holder alongside South Korea. The dataset draws on the USGS Mineral Commodity Summaries 2019-2026 and reports scrap and flake mica reserves in metric tons. Reserves are estimated quantities of scrap and flake mica that can be economically extracted under applicable conditions. Listed reserves totaled 13,720,000 metric tons in 2025.

South Korea holds 12,000,000 metric tons, nearly eleven times China's 1,100,000. Türkiye ranks third with 620,000, leaving a 10,900,000-ton gap between the top two countries. The source gives the world total only as “Large”.

#	Country	2025 (metric tons)
1	South Korea KR	12,000,000
2	China CN	1,100,000
3	Türkiye TR	620,000

South Korea's 1,000,000 addition exceeded Türkiye's entire 620,000 stock.

South Korea returns to 12 million tons

South Korea reported 12,000,000 metric tons in 2018 and 2019, then 11,000,000 from 2020 through 2024 before returning to 12,000,000 in 2025, a 9.1% increase. It was the only reported change in the three-country table that year, bringing South Korea back to its 2018 level.

China enters the ranking in 2023

China first appears in 2023 with 1,100,000 metric tons and remains at that level through 2025. That gives China about 8.0% of the listed 2025 total, compared with roughly 4.5% for Türkiye.

China's arrival pushes Türkiye to third

Türkiye reported 620,000 metric tons in every year from 2018 through 2025. It ranked second until China's 2023 entry moved it into third place, even though Türkiye's reported reserve figure remained unchanged.

Methodology

Figures come from the USGS Mineral Commodity Summaries 2019-2026, with 2025 values estimated. Units are metric tons of scrap and flake mica, as reported by the source. This page measures scrap and flake mica; sheet mica is published as a separate series and the two are not interchangeable. Empty means the source reported no value; 0 means the source reports zero. The source’s world total, where published, may be rounded, approximate, a lower bound, or a textual estimate, so shares are computed against the sum of the listed countries. Reserves and production are different measures and should not be combined without equalizing units.
