Latin American mining boom sparks air‑pollution debate and copper substitution warning

New lithium mining projects in Argentina are intensifying a debate over air‑pollution from dust, drilling, blasting and heavy‑machinery traffic. Specialists and local communities are demanding transparent, continuous monitoring and public reporting of particulate emissions, and are urging the adoption of mitigation technologies such as road‑spray irrigation and real‑time particle sensors.

At the same time, a Chilean mining academic warned at the Exponor 2026 fair that persistently high copper prices could trigger manufacturers to replace copper with cheaper alternatives such as aluminium, undermining long‑term demand. He argued that expanding copper production in the region would help keep prices stable and protect the metal’s market position, emphasizing cooperation with neighbouring producers in Peru and Argentina.
