• How Is Quartz Extracted? Sciencing

    Geologically, quartz crystal deposits were formed millions of years ago. They are mined for industrial uses in clocks, computers and radios, and are also valued as decorative items and for jewelry. Arkansas is one of the places in the world with sufficient quartz deposits to justify commercial mining operations.

  • What Is The Environmental Impact Of The Mining Industry ...

    Air PollutionWater PollutionDamage to LandLoss of BiodiversityAir quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining. Wind erosion and nearby vehicular traffic cause such materials to become airborne. Lead, arsenic, cadmium, and other toxic elements are often present in such particles. These pollutants can damage the health of people living near the mining site.
