SEOUL, Nov. 5 (UPI) — Non-ferrous metal giant Korea Zinc said Tuesday it nearly doubled its profit in the third quarter of 2025 overa year ago, driven by strong demand across its product lines.

Korea Zinc reported $2.87 billion in revenue during the July-September period, up 29.7% year-on-year, for an operating income of $189 million, up 82.3%. The company said that it has remained profitable for 103 consecutive quarters since 2000.

The Seoul-based corporation said the strong sales of critical raw materials, including antimony, indium and bismuth, as well as precious metals, boosted performance during the three-month period.

Through its integrated smelting process for zinc, lead and copper, Korea Zinc also recovers about 10 by-products of critical raw materials and precious metals, such as gold and silver.

Korea Zinc said that gold and silver contributed about $2.5 billion to revenue during the first nine months of this year, as metal prices remained strong.

The world’s largest zinc manufacturer has also expanded its portfolio of strategic materials. Antimony, indium and bismuth are classified as “critical minerals” by Washington and Seoul.

Early this year, it started exporting antimony, a vital component in electronic and defense production, to the United States. Its global sales of antimony reached $173 million so far this year.

In August, Korea Zinc signed a memorandum of understanding with Lockheed Martin to supply germanium, another critical mineral, to the U.S.-headquartered defense contractor.

“On the back of proactive investments and a diversified portfolio, our strategic minerals and precious metals business did well. New growth areas such as resource recycling are also on a stable trajectory,” Korea Zinc said in a statement.
