The closure of the Strait of Hormuz, alongside China’s decision to halt exports of sulfuric acid from May 1, is tightening global supplies of a critical chemical used in copper production. The combined effect is placing mounting pressure on both the agricultural and mining industries, which depend heavily on acid-intensive processes.
Sulfuric acid is essential for copper extraction through heap leaching and smelting. With the Strait of Hormuz—a key transit route for oil and chemicals—disrupted, and China, a major producer of sulfuric acid, restricting exports, prices are expected to rise. This could increase operational costs for copper mines and delay projects, potentially affecting global copper supply. Copper is vital for electrical wiring, construction, and renewable energy technologies, making this development particularly significant.
Mine development companies like Numa Numa Resources Inc. are likely to study these supply constraints to improve their resilience. The situation highlights the vulnerability of global supply chains for critical inputs. As acid supply constraints play out, the mining industry may need to explore alternative sources or technologies to mitigate risks.
