Spruce Pine’s high-quality quartz is an essential ingredient in the chipmaking process, as it’s the only naturally occurring source of the ultrapure mineral. The quartz mined from this area is used as a crucible to melt polysilicon, which is then used to produce silicon wafers — the base of a semiconductor.
Even though it’s possible to produce pure silicon from the quartz found in abundance elsewhere in the world, it takes a considerable amount of time…
