Why it issues: Extremely-high-purity quartz is a vital part to semiconductor chips, and the one locations on the earth that may meet this want are two mines in a small North Carolina city. The mines’ proprietor, Sibelco, is investing $700 million to increase capability, however is that sufficient to maintain up with AI-fueled chip demand?
Spruce Pine is a small city about two hours drive northwest of Charlotte, NC. You may get to the final space through various methods, relying in your level of origin, however for the final stretch of the journey, you have to journey down Fish Hatchery Rd. It is a two-lane rural freeway, as depicted in Google Maps, set amid a pleasing scenic backdrop.
It is on this street that the trendy financial system rests, based on Wharton affiliate professor Ethan Mollick, who teaches innovation and entrepreneurship and in addition examines the results of synthetic intelligence on work and schooling. That is as a result of the street runs to the 2 mines which can be the only provider of the quartz required to make the crucibles wanted to refine silicon wafers.
This isn’t the primary time these mines – owned by Sibelco, which mines, processes, and sells specialty industrial minerals – have been highlighted as integral not solely to the worldwide semiconductor trade but in addition to the photo voltaic photovoltaic markets.
Ed Conway raised the problem in his ebook, Materials World, printed final summer time. Even earlier than that, varied media have coated the obscure mines. Mollick raised it once more in a latest Tweet, emphasizing its strategic significance. If the mines had been by some means to cease working, “it could doubtless [be] a couple of years of main disruption whereas methods to generate alternate options had been scaled up. However the disruption could be fairly catastrophic.”
Sure, that is precisely what the quoted passage says. It could doubtless a couple of years of main disruption whereas methods to generate alternate options had been scaled up. However the disruption could be fairly catastrophic.

It’s an alarming prospect to ponder, and it’s honest to wonder if Mollick is indulging in a little bit of hyperbole. However there isn’t a denying the truth that digital units world wide include a small piece of Spruce Pine’s distinctive ultra-high-purity quartz. “It does boggle the thoughts a bit to contemplate that inside practically each cellular phone and laptop chip you will discover quartz from Spruce Pine,” Rolf Pippert, mine supervisor at Quartz Corp, a number one provider of high-quality quartz, tells the BBC.
How did this unassuming North Carolina city acquire such an outsized position within the international semiconductor provide chain? The reply is its distinctive mineral deposits, which fashioned 380 million years in the past through the collision of Africa and North America. The extraordinary warmth and lack of water throughout their formation created quartz rock of unparalleled purity. These rocks are extracted from the bottom and changed into quartz gravel, which is then processed right into a superb sand. The silicon is separated from different minerals after which goes by way of a closing milling. The ultimate product is a powder that’s shipped to refineries.
The inexorable march of synthetic intelligence will proceed to drive demand for chips and the supplies in its provide chain. One query to ponder is whether or not Spruce Pine can sustain.
Sibelco, after all, has famous these tendencies as nicely and final yr introduced a $200 million funding to double excessive purity quartz capability at its Spruce Pine facility, citing demand for the product, which is bought underneath the model title IOTA. It can make investments an extra $500 million between 2024 and 2027.
