Context

Geologists say they have identified a new deposit in central China that can produce high-purity quartz comparable to the quality produced at a critical world-leading mine in the United States. The high-purity quartz from the Chinese deposit is described as having “highly similar” properties to the resources produced at North Carolina’s Spruce Pine, which is crucial to the global production of solar panels and semiconductors. In the US, there is a growing call from the industry to use high-purity...
