Purity of China quartz deposit ‘highly similar’ to US Spruce Pine standard: study

Geologists say they have identified a new deposit in central China that can yield high-purity quartz comparable to the quality produced at a critical world-leading mine in the United States. The 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 s
