    This process utilizes magnetic and float separation to remove impurities. After the sand has been washed and dried and contaminants have been removed, it is screened. In this process, sand is separated according to grain size and stockpiled for future blending. These numerous demands for sand require mining of our dunes and other sand resources.

  • Coal Mining and Processing Energy Trends Insider

    Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
