  • Boundary Waters (BWCA) Sulfide Mining

    Sulfide mining is the process of extracting trace amounts of copper, nickel and other metals from sulfide-bearing ores, which produces sulfuric acid. This is the same as battery acid. In addition to acidifying lakes and rivers, sulfuric acid leaches out heavy metals such as mercury, lead, arsenic and other toxins from the rock to produce acid

  • Copper Mining Process

    The process of mining copper begins with drilling and blasting. Large drilling rigs bore a carefully designed pattern of holes approximately 12 inches in diameter and 60 feet deep into the rock. The holes are filled with an explosive compound of fuel oil and ammonium nitrate which blasts thousands of tons of ore in a single detonation.
