Recognition of Minsur’s innovation and sustainable commitment

In 2024, Minsur was awarded important recognitions for its Circular Tin project: the case of reusing tailings from the San Rafael mining unit in Puno (plant B2). These distinctions are for Business Creativity (the most important business award in the country) and Peru for the Sustainable Development Goals (SDG), promoted by the UN Global Compact and other recognized institutions.

What does this project consist of and what makes it so innovative? Our Project Director, Yuri Gallo, explains it to us.

1. What were the main challenges in implementing the B2 Tailings Recycling Plant and how did you overcome them?

The main challenge was to develop an innovative technology to recover tin from tailings, which led us to an international collaboration with Australia, Canada, Bolivia, and Peru between 2004 and 2009. From 2010, we carried out tests in a pilot plant, and, between 2015 and 2017, we designed and built the B2 plant, with an investment of US$ 174 million and more than 4 million hours worked without accidents.

2. How does the B2 plant guarantee its minimum environmental impact and sustainability in its processes?

The plant follows high sustainability standards, with Minsur being a member of the International Council on Mining and Metals (ICMM). It has a circular economy approach, optimizing resources and reducing waste. The plant recirculates 93% of the water used and avoids the use of explosives, which minimizes the water and carbon footprint. In addition, it complies with environmental regulations, such as ISO 14001, guaranteeing the quality of the water returned to the environment.

3. What impact has the B2 plant had on the local economy of Puno and nearby communities?

The plant has generated local employment, with 60% of its staff coming from nearby communities such as Antauta and Ajoyani. It has also boosted the local economy through the purchase of goods and services, creating more than 1,500 indirect jobs. The operations have funded social investments and contributed significantly to the mining royalty.

4. What are the long-term plans for the B2 Plant and its technologies?

The plant will continue to process B2 tailings until 2028 and is considering expanding the technology to other fine minerals from new deposits. B2 technology could be adapted to process other tailings deposits at the San Rafael mining unit, expanding its positive impact on sustainability and the local economy.
