Korea Zinc(010130)

HQ KR

Korea Zinc Co., Ltd. (Seoul; KRX: 010130; ~$9B revenue) is the world's largest single-site zinc, lead, and silver smelter operator and the world's largest non-Chinese indium refiner. Indium is recovered as a byproduct at its Onsan smelter in Ulsan, South Korea — the only facility in Korea with an indium processing line. Korea Zinc produces ~150 tonnes of indium annually at 99.999% purity (vacuum-packed 5-kg bars), meeting roughly 11% of global demand outside China. About 90% of Korea Zinc's indium output is exported to the US, Japan, and Taiwan — making it the primary indium supplier for US and Taiwanese display/semiconductor manufacturers seeking non-Chinese supply. The Onsan smelter also produces gallium and antimony; Korea Zinc has invested heavily to diversify into critical minerals as a strategic counterweight to Chinese dominance.
