SEOUL, Dec 16 (Reuters) - South Korean private equity firm MBK Partners and metal smelter YoungPoong Corp requested an injunction at a local court to block Korea Zinc's share sale plan to fund the construction of a smelter in the U.S., MBK said in a statement on Tuesday.
Korea Zinc said on Monday it would build a $7.4 billion critical minerals refinery in Tennessee that will be funded largely by Washington.
MBK and YoungPoong are major shareholders of Korea Zinc.
