Manganese

Manganese mines and prospects in Virginia

Manganese is a hard, grayish-white, brittle metal with the chemical symbol Mn.  Three common manganese minerals found in Virginia are psilomelane, pyrolusite, and manganite.  Manganese is an essential ingredient in steel.  It is also used in dry-cell batteries and has a variety of chemical applications.

Year of first production in Virginia: 1834
Location of first production in Virginia: Paddy Run, Frederick County
Year of last production in Virginia: 1959
Location of last production in Virginia: Crimora Mine, Augusta County
Total cumulative production in Virginia: unknown
Current annual production in Virginia: none

The manganese minerals found in Virginia are generally manganese oxides, psilomelane, pyrolusite, and manganite; these are sometimes associated with iron oxide deposits.  Manganese deposits have been found in Frederick, Shenandoah, Bath, Alleghany, Botetourt, Craig, Montgomery, Giles, Bland, Tazewell, Russell, Washington, Scott, Wise, Smyth, Wythe, and Augusta counties.

The Crimora Mine, located in Augusta County, was the largest producer of manganese in the United States.  The Crimora Mine operated as early as 1867, and continued off and on until 1959. The U.S. government purchased and stockpiled manganese ore produced from Augusta County during the 1950s at Riverville, Amherst County.
