Leaching Gold In Manganese Ore

  • A Method for Leaching or Dissolving Gold From Ores or

    It is known that gold can be efficiently leached from gold- bearing ores using a mixture of hydrochloric acid, ferric chloride, and manganese dioxide.12 The chemical reaction involved during theTwo-stage leaching of manganese and silver from manganese,CaS was used for the reduction of manganese oxides in manganese-silver ores. • S 2 O 3 2 − produced in situ in reduction procedure can be used for Ag leaching.. The leaching efficiencies of Mn and Ag can reach 98.0% and 92.0%, respectively.
