It is necessary to apply for a mining license from the national or local natural resources department. In the application process, it is necessary to evaluate the mine location, resources, mining plan, environmental protection measures and other information. The exploitation of Shi Ying and the purification of high-purity quartz sand will have an impact on the environment. Therefore, before applying for a mining license, it is necessary to conduct an environmental impact assessment and obtain special approval for environmental protection. The assessment includes the impact of mining on the surrounding environment, land reclamation and ecological compensation measures. Only after passing the examination can a mining license be obtained.
