Chile's Smelter Capacity Stagnant Amid Rising Competition
Chile is home to about a quarter of global copper concentrate production but only smelts around 4.2% of world output. This discrepancy has significant implications for the country's economy and mining industry. According to Cochilco, Chile's five major smelters are currently operating at around 60% capacity, with Codelco's Caletones, Chuquicamata, and Potrerillos, Glencore's Altonorte, and Anglo American's Chagres being the main facilities.
The current underutilization of Chilean smelters is partly due to tight custom smelting markets and rising competition from Asian capacity. The global TC/RCs (treatment and refining charges) have fallen towards zero or negative, making it difficult for Chilean operators like Codelco and ENAMI to compete.
Cochilco urges that any new smelter builds in Chile must undergo strict technical, economic, environmental, and operational viability tests. The state-owned ENAMI is also progressing a modernization program for its ageing smelter plant. However, the global projects under consideration could add 8.2 Mt/y of fine copper smelting capacity by 2041, mainly in Asia.
The current price levels of around $6.78/lb and near record highs suggest that Chile's current 4% smelting share leaves value capture from this price environment disproportionately in the hands of Asian smelters rather than Chilean operators.
