United States of America v. Reserve Mining Company
After the discovery of taconite in the late nineteenth century, scientists struggled to find ways to extract iron ore from this sedimentary rock, which contains 25 to 30 percent iron. The process that was eventually developed involves crushing the hard rock into a powderlike consistency. The iron ore is then removed with magnets and turned into pellets.
