Yunnan Tin Company mines (company total): a tin operation in China

Yunnan Tin Company mines (company total) is a group of mines producing tin in Gejiu (Honghe) and Dulong (Wenshan), Yunnan, China, operated by Yunnan Tin. The sources report 31,788 tonnes ('锡原矿金属 / tin raw-ore metal', production quantity) for CY2025; the basis is company total, as reported by the operator. The sources do not give a whole-operation figure in tin content that can be compared with world output, so no share is computed.

Who owns and operates it?

How much does it produce?

Reported output of Yunnan Tin Company mines (company total)
Period	Output	Basis	Where in the source
CY2025	31,788 tonnes ('锡原矿金属 / tin raw-ore metal', production quantity) Tin metal contained in raw ore mined, before concentration. The same table prints 24,363 t for copper and 120,703 t for zinc raw-ore metal.	company total, as reported by the operator	printed p.28 (PDF p.33), table under the Shenzhen Stock Exchange solid mineral resources disclosure requirement, row 锡原矿金属, column 生产量 (production), 2025 · Yunnan Tin Company Limited (云南锡业股份有限公司)
CY2024	31,173 tonnes ('锡原矿金属 / tin raw-ore metal', production quantity)	company total, as reported by the operator	printed p.28 (PDF p.33), same row, 2024 column · Yunnan Tin Company Limited (云南锡业股份有限公司)

Between CY2024 and CY2025 the reported figure rose by 2.0%, in the same unit and on the same basis.

Status: operating, as of 31 December 2025.

The measure is tin metal in raw ore as mined, which is an earlier stage than tin contained in concentrate; the report prints no tin concentrate output.
The company is also a smelter. The same report prints tin ingot production of 86,233 t for 2025 (printed p.28) and a tin self-sufficiency rate of 28.47% for tin concentrate (printed p.15); neither is mine output.
The company-level figure covers mines in two areas, Gejiu in Honghe and Dulong in Wenshan, and the report prints no split between them.
USGS prints 71,000 t of tin for China in 2025 (estimated).
The figure is tin in raw ore, an earlier stage than tin in concentrate, so no share of world output is computed.

Method and limits

Reported, not estimated. Output is the figure the operator or owner published, in the unit it used. This site does not estimate output where none is published.
Shares. A share divides output in tin content by the USGS world or country total for 2025. Where the operator's year is a fiscal year or the unit is a concentrate or a carbonate equivalent, the share is approximate or not given.
Whole operation or owner's share. The basis column says which. A joint venture's output is never counted twice.
Partial list. Only operations with a published figure are listed, so the rank is among those on this site, not among every tin mine. Shares of a country's output mix periods and bases, so treat them as indicative.
