Apr 6, 2022A government program to stockpile manganese led to subsidies of the mining beginning in 1952, but the program ended in 1959 when the desired amount had been stockpiled. The last load of manganese ore produced in the district was shipped in August 1959, and then all manganese production ceased.

Abstract Removal of manganese (Mn) from mine drainage is difficult due to the abnormal chemistry of the element. The removal requires the oxidation of Mn (II) (the form found in mine drainage) to the more oxidized forms (Mn (III) or Mn (IV)). The more oxidized forms exist only as solids and will not return to Mn (II) spontaneously.
