Mine drainage is formed when pyrite an iron sulfide is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage. The acid runoff further dissolves heavy metals such as copper, lead, and...

Solution mining through injection wells is an option that can minimize the environmental footprint and potential impact to surface water compared to more traditional mining processes. To prevent contamination of ground water which in many cases is a USDW by Class III wells, more fluid is extracted than is injected in solution mining processes.
Since minerals are nonrenewable recycling can reduce the amount of mining and extracting, and reduce waste by moving from step 5 in the mining process back to step 3. Impoundments built to store tailings and to keep pollutants from leaching out of the tailings and contaminating soil and ground water.
