Quartz Deposit Purity in Central China 'Highly Similar' to US Spruce Pine Standard: Study The discovery of a high purity quartz deposit in central China has generated significant interest in the global tech industry.
The Xiaohuaguo site in Hubei Province contains quartz with properties similar to those found at North Carolina's Spruce Pine, a standard against which high purity quartz is often measured.
This development comes as the industry seeks alternative sources following China's rare earth export ban. The US has been exploring ways to utilize high purity quartz as a countermeasure.
