Why it issues: Extremely-high-purity quartz is a vital part to semiconductor chips, and the one locations on this planet 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 demand?
Spruce Pine is a small city about two hours drive northwest of Charlotte, NC. You will get to the overall space through various methods, relying in your level of origin, however for the final stretch of the journey, it’s good 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 highway that the trendy economic system rests, based on Wharton affiliate professor Ethan Mollick, who teaches innovation and entrepreneurship and likewise examines the results of synthetic intelligence on work and training. That is as a result of the highway runs to the 2 mines which are 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 business but additionally to the photo voltaic photovoltaic markets. Ed Conway raised the difficulty in his ebook, Materials World, printed final summer season. Even earlier than that, numerous media have lined the obscure mines. Mollick raised it once more in a current Tweet, emphasizing its strategic significance. If the mines had been someway to cease working, “it could doubtless [be] just a few years of main disruption whereas strategies to generate options had been scaled up. However the disruption can be fairly catastrophic.”
Sure, that is precisely what the quoted passage says. It will doubtless just a few years of main disruption whereas strategies to generate options had been scaled up. However the disruption can 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 is no such thing as a denying the truth that digital gadgets around the globe comprise 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 cellphone and pc chip you may 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 achieve such an outsized function within the international semiconductor provide chain? The reply is its distinctive mineral deposits, which shaped 380 million years in the past in the course of the collision of Africa and North America. The extreme 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 tremendous sand. The silicon is separated from different minerals after which goes by means of a remaining 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, in fact, has famous these traits as properly 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 below the model title IOTA. It’ll make investments an additional $500 million between 2024 and 2027.
