Experiment 1: The Effects of Coal Mining Coal mining‚ particularly surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp. Activated
