The closure of the Strait of Hormuz, combined with 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 leaching copper from ore in solvent extraction-electrowinning (SX-EW) operations, a method that accounts for a significant portion of global copper output. The Strait of Hormuz, a key transit point for sulfur and other raw materials used in acid production, has seen disruptions amid heightened geopolitical tensions. Meanwhile, China, the world's largest producer and exporter of sulfuric acid, has imposed export restrictions to prioritize domestic supply, further tightening availability.
Industry analysts warn that the shortages could lead to higher production costs and reduced output for copper mines, particularly in regions like South America and Africa that rely on imported acid. The agricultural sector also faces challenges, as sulfuric acid is a key ingredient in phosphate fertilizers. With the spring planting season underway in many regions, farmers may encounter higher prices and limited supply of fertilizers, potentially affecting crop yields.
As acid supply constraints play out, mine development companies like Numa Numa Resources Inc. are likely to pick up lessons and plan how to mitigate such risks in the future. The situation underscores the vulnerability of global supply chains to geopolitical events and policy shifts.
