  • MANGANESE ORES: FORMATION AND DISTRIBUTION - Nevada .

    Manganese minerals also frequently occur as gangue minerals in connection with silver ores. A manganese ore to be of commercial value should contain at least 40 per cent of metallic manganese and be low in percentages of phosphorus and silica.

  • US4816235A - Silver and manganese recovery using acidified ...

    A method for obtaining silver and manganese metal from a silver-manganese ore includes the step of leaching the ore with acidified thiourea. More specifically, the method includes the step of leaching the ore with an acidic thiourea solution to form a leach liquor containing compounds of silver and manganese and an insoluble ore residue.
