Over the period, for example, the United States has (1) consistently relied on imports to provide between 77 percent and 100 percent of its fluorspar
needs--a key ingredient in the manufacture of aluminum, gasoline, steel, and uranium fuel; (2) fluctuated in its reliance on imports to meet its need for copper, importing copper in most years and providing net exports in 1975 and 1991; (3) decreased its reliance on imports of nickel from a high of 80 percent in 1978 to a estimated low of 17 percent in 2007; (4) consistently been a net exporter of gold between 1982 and 2003; and (5) been a net exporter of magnesium metal until 1997, when the United States began to import magnesium metal.
Under permission granted in 1952, the operator can only extract limestone as a by-product of extracting fluorspar
