San Rafael B2 tailings reprocessing plant: a tin operation in Peru
San Rafael B2 tailings reprocessing plant is a tailings reprocessing plant producing tin in San Rafael Mining Unit, Puno Department, Peru, operated by Minsur. The sources report 7,782 t, 'Sn fines' (the report calls it tonnes of contained tin) for CY2025; the basis is B2 plant only, as reported by the operator. In tin content, whole-operation output for CY2025 is 7,782 tonnes: about 2.7% of world tin output in 2025 and about 24% of Peru's; it is one of 6 operations on this site whose output can be stated in tin content.

How the tin-content figure is worked out. Minsur reports 7,782 tonnes of contained tin from the B2 tailings reprocessing plant in 2025. The plant is separate from the San Rafael mine line (26,037 t), so the two are not counted twice. World mine production of tin in 2025 was 290,000 tonnes (USGS Mineral Commodity Summaries 2026); Peru produced 33,000 tonnes.
Status: operating, as of 30 September 2026.
- The plant recovers tin from the historical tailings of the San Rafael mine. The report lists it in its own production table, which has a mine row (915,235 t of ore extracted in 2025 at 1.22% Sn).
- The integrated report says the plant operated within the production and quality parameters established in the project design in 2025 (PDF p.31).
- Together with San Rafael (26,037 t) the two Minsur lines (33,819 t) are slightly above USGS's rounded estimate of 33,000 t for Peru, so the shares of Peru's output on these two pages are approximate.

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.
