Michael Tost, head of the Department of Mining Engineering and Economics of Mineral Resources at Montan University in Leoben, emphasized that the proposed lithium mine in the Jadar Valley would operate as an underground mine, reaching depths of 400 to 700 meters. This design ensures minimal impact on surface soil, drinking water and groundwater at those depths.
In an interview with Demostat, Tost, who has extensive mining industry experience and previously led the Mining and Metals Sector at the World Economic Forum in Davos, stressed the importance of relying on factual data over opinions from social media.
Key points on mining impact
Tost clarified that the mining operation would not involve large surface excavations, thus allowing agricultural activities to continue above ground. He reiterated the need to focus on factual information rather than social media speculation.
The mine will utilize closed systems situated on concrete bases, known as tankvans, constructed to industry standards to minimize pollution risks. Should any leaks occur, an additional protective layer would prevent contaminants from reaching the ground.
Furthermore, waste will be managed responsibly, stored in specially designed landfills that incorporate protective layers to avoid environmental harm. Tost noted that the groundwater at mining depths is not suitable for drinking or agricultural use, with wells located much shallower, at 20 to 30 meters.
The mine water will be collected and purified, allowing for recycling in later stages of mining operations. Tost explained that sulfuric acid, used solely in closed systems for ore processing, will be minimized to avoid excess waste and cost.
Adequate measures, including scrubber filters, are planned to prevent sulfuric acid fumes from entering the air, further mitigating environmental risks.
Tost highlighted the responsible mining practices being adopted, including Rio Tinto’s approach to waste management through dry compacted storage—a relatively new technology. He noted that Montan University is committed to advancing research in this area to support sustainable practices in the mining industry.
