Students Learn About Remediation Process at Sierra Pintada

The Ministry of Energy and Environment of Mendoza, through its Mining Directorate, organized an educational visit to the Sierra Pintada Mining and Processing Complex in San Rafael with first-year students from the Mining Operations Technician program at the Faculty of Applied Sciences to Industry of the National University of Cuyo. The activity, framed within the Mining First-Hand program, allowed students to gain in-depth knowledge of the environmental remediation process being executed at the facility, integrating academic training with territorial experiences in the provincial mining value chain.
Environmental remediation at Sierra Pintada: technical scope and oversight
The tour of Sierra Pintada Complex facilities exposed students to various aspects of environmental remediation, a critical phase in mine closure and the transition toward sustainability standards. The process implemented at the deposit includes pit water treatment, solid waste management, and recovery of residual uranium, tasks carried out through facilities specifically designed with advanced environmental protection and control systems.
Execution of these tasks operates under continuous supervision by provincial and national agencies, with periodic monitoring and external audits coordinated by the Faculty of Applied Sciences to Industry. This multi-layered oversight scheme ensures that remediation processes comply with rigorous environmental standards and national regulations applicable to uranium mining legacy sites.

UNCuyo students toured Sierra Pintada facilities undergoing remediation.
The activity included specialized technical personnel, including representatives from the Environmental Management and Oversight Directorate, the Sustainable Development Area of the Mining Directorate, and the Mining Environmental Police of San Rafael. The technical team accompanied the tour with specific objectives: assess circuit safety conditions, identify improvement opportunities, and formulate recommendations to strengthen future educational visits on site.
Educational perspective: linking territory and academic training
Leonardo Fernández, director of Environmental Management and Oversight, underscored the strategic importance of these experiences: "This type of experience allows students to engage with mining activity from the territorial perspective and learn concrete processes that are part of the value chain, including environmental controls and remediation tasks." The statement reflects institutional policy aimed at fostering technical and environmental literacy among future generations of mining professionals.
From the perspective of sector oversight and promotion, Jerónimo Shantal, Mining Director, emphasized the state's facilitating role: "We support companies and facilities so these tours can be developed safely and with content that proves useful for student training."
This formulation underscores that the initiative is not merely extractive of knowledge, but rather involves prior technical support from regulatory agencies.

Mining First-Hand
The Mining First-Hand program seeks to strengthen the linkage between the mining sector and educational institutions through a diverse portfolio of activities: guided tours, visits to productive facilities, technical seminars, and other experiential learning. The initiative aims for students and faculty to gain comprehensive understanding of Mendoza's mining value chain, including processes, technologies, environmental controls, services, and professional profiles demanded by industry.
To this end, the Mining Directorate maintains an open call for companies, projects, and facilities directly or indirectly linked to mining activity wishing to participate in the initiative and offer spaces for educational visits by students from schools, technical institutes, and universities. The program is not limited to copper, gold, or other traditional minerals, but encompasses the entire chain, from exploration through remediation and complementary sectors such as mineral processing.
A central aspect of the proposal is the prior technical support offered by the Mining Directorate. This preliminary work includes comprehensive assessment of safety conditions and infrastructure at each facility, as well as specific recommendations to adapt tours to the characteristics of the student groups visiting. Javier Frias, coordinator of the Sustainable Development Area of the Mining Directorate, explained the philosophy behind this approach:
The proposal does not simply consist of opening facility doors. We seek to generate quality educational experiences where students can learn how each activity functions, what its processes are, and which professionals are involved. For that reason, it is important to work previously with companies and analyze the conditions necessary for visits to be safe and have true educational value.
Expansion to secondary mining: technical visit to Yesos Valle Nevado
Expanding the territorial and sectoral reach of the program, Mining Directorate teams also conducted a technical visit to the gypsum plant at Yesos Valle Nevado, where they toured facilities and analyzed conditions for developing future educational visits. This inclusion of secondary mining demonstrates that the program transcends metallic minerals to encompass industrial and non-metallic minerals, an economically significant segment in Mendoza.
During the Yesos Valle Nevado tour, students learned about the various stages of mineral processing and finished products manufactured at the plant. Among these are gypsum for construction and an agricultural gypsum line, used as a fertilizer and applied in regional crops and agricultural operations. This type of characterization allows students to understand the diversification of uses and markets for a single base mineral.
As at Sierra Pintada, the technical visit identified aspects related to future tour safety and proposed improvements aimed at creating appropriate conditions to receive student groups. Frias noted: "Each facility presents different characteristics and risks, so prior assessment is fundamental. The visit to Yesos Valle Nevado allowed us to learn about the production process, identify improvement opportunities, and advance a proposal enabling students to engage with this segment of mining activity as well."
Consolidating the mining education network and future perspectives
Through these actions, Mining First-Hand continues expanding the network of companies and facilities linked to mining activity that can become learning spaces. The institutional objective is multidimensional: bring concrete, territorial experiences to the educational community, contribute to training future professionals and technicians required by the sector, and strengthen the fabric of linkages between academic institutions, mining companies, and environmental oversight agencies.
The methodology adopted by the Mining Directorate establishes a quality standard for educational visits that transcends mere exposure; it involves prior diagnostic work, development of safety protocols, curriculum design of content, and subsequent evaluation. This comprehensive approach is consistent with international policies on corporate social responsibility and technical education in extractive industries, where training of local human capital is considered a strategic sustainability asset.
