Yunnan Tin is one of the world’s largest tin producers, headquartered in Yunnan Province, China. The company operates integrated mining, smelting, and refining facilities, supplying refined tin and related products to global electronics, soldering, and industrial markets. With extensive mineral reserves and advanced processing capabilities, Yunnan Tin plays a strategic role in both domestic and international tin supply chains. Its vertically integrated operations ensure stable production output, technological efficiency, and strong export orientation within the global non-ferrous metals sector.

Yunnan Tin was established in 1883 in Gejiu, Yunnan Province, making it one of the oldest tin producers in China. The company developed around the rich tin deposits of southwestern China and became a key supplier during the early industrial period.

Following the founding of the People’s Republic of China in 1949, the enterprise was reorganized under state ownership and expanded into integrated mining, smelting, and refining operations. By the late 20th century, it had become one of the world’s largest tin producers.

During the 2000s, modernization programs and international market expansion strengthened its global export profile. Yunnan Tin continues to play a major role in global tin supply chains.

Primary Mining Regions
Yunnan Tin operates primarily in Yunnan Province, China, particularly in the historic tin-producing city of Gejiu. The region is internationally recognized for its extensive tin reserves and long-standing mining heritage. Additional exploration and resource development projects are located across southwestern China, strengthening domestic mineral security and supply continuity.

Infrastructure and Processing Facilities
The company maintains integrated underground and open-pit mining sites supported by advanced smelting and refining facilities within Yunnan Province. Concentrate processing plants are directly linked to metallurgical complexes, ensuring efficient material flow. Rail connections and highway corridors connect production centers to major logistics hubs and export ports in southern China, supporting international shipments.

Strategic Geographic Advantage
Its southwestern location provides direct access to mineral-rich zones and proximity to Southeast Asian trade routes. Strong transport connectivity and established export infrastructure position Yunnan Tin as a major supplier to global electronics and soldering industries.

In 2024, Yunnan Tin maintained stable tin concentrate production while focusing on refining efficiency improvements at its Yunnan smelting facilities. Operational upgrades emphasized cost optimization and improved recovery rates to support global electronics demand.

During 2024, the company strengthened environmental management programs and introduced energy-saving measures across processing plants. Supply chain coordination with domestic and Southeast Asian customers remained a strategic priority.

In 2025, Yunnan Tin continues prioritizing production stability, export reliability, and modernization of metallurgical systems to reinforce its global tin market position.
