Korea Zinc talks to US tech companies about removing rare earths from waste data centres

Chairman of firm says that it has made acquisitions related to the company's business.

The US plans a $7.4 billion smelter.

The US will reduce its reliance on Chinese rare earths through a number of projects

By Heejin Kim

SEOUL, 12 March - Korea Zinc has been in discussions with major U.S. tech firms about recycling data centre wastes and extracting rare earths. This is part of a U.S. effort to reduce its reliance on Chinese minerals.

In an interview, Yun B. Choi, the Chairman of the firm, said that it is one of 'the world's largest smelters. It also hopes to secure solar and battery panel wastes containing rare earths and metals, which are needed in areas such as electronic, electric vehicles, defence and energy.

The initiative will provide the U.S. with another source of rare Earths beyond the U.S.'s single mine, and its main supplier China. China produces 90% of all rare earths produced in the world and has restricted?exports as part of a tariff-war sparked by the U.S.

Choi stated that the U.S. Government has continuously advocated for recycling of critical minerals because it is 'aware' that a large amount of these minerals were exported via multiple countries to China. He said that for the past two-years, "we have quietly researched technologies to 'extract rare Earths.

Choi refused to reveal the amount or technology firms involved, but said Korea Zinc had invested in recycling. This included?buying a scrap metal trader and electronic waste recycler.

He said: "If we could?provide a process or solution?to extract and refine new rare earths, as well as provide them in the United States I believe the business value will be significant."

NEW U.S. SMELTER

The South Korean company announced in December that it would build a critical minerals smelter worth $7,4 billion in Tennessee. This is the first U.S. smelter to be built since the 1970s, and the first one funded by the U.S. Government.

Korea Zinc said that the smelter would produce 540,000 tons of non-ferrous minerals, including 11 critical metals such as gallium, antimony and germanium.

Choi, citing the U.S. national security as a primary factor, said that the U.S. attitude towards critical minerals had changed dramatically after China implemented its export control on rare Earths in April 2025.

Korea Zinc posted a record operating profit of 1.2 trillion won (813 million dollars) in 2013, driven by the sale of antimony. The U.S. lists this metal as "critical" for nuclear weapons and military applications.

Choi said, "Last was the year of antimony." According to data from the U.S. Geological Survey, the average price of anthracite in 2025 will be $25 per pound. This is more than twice as much as it was in 2024.

Choi stated that Korea Zinc aims to achieve profit margins between 17% and 19% at the new smelter. Data from Seoul-based DB Securities showed that this would be higher than its 51-year old Korean refinery.

Choi stated that the U.S., as a joint investor, is providing support. He cited fast-tracked permit approvals and expectations for?guaranteed minimal prices? for U.S. vital minerals projects.

Choi said that the firm plans to begin construction early in 2027, and that the smelter will break even in a year after it begins operations in 2030.
