One of the two companies that manufacture high-purity quartz used for making semiconductors and other high-tech products from mines in a western North Carolina community severely damaged by Hurricane Helene is operating again.

Two facilities that produce high-purity quartz essential in semiconductors, solar panels, and fiber-optics have been shut down.

The owner of a North Carolina quartz mine that’s a key source for high-purity quartz used in global semiconductor manufacturing said its operations sustained only minor damage in the wake of Hurricane Helene.

The Sibelco mine in North Carolina is one of the most crucial sites to the global production of semiconductors.
