The Possibilities of Hydrometalurgical Using of Manganese Ore from Bihać Region

Preliminary results of hydrometalurgical treatment of manganese ore from Bihać region indicate possibility of use this ore for metallic manganese production. Hydrometallurgical leaching of manganese oxide ore by concentrate sulphuric acid as leaching agent is initial stage in process of metallic manganese production. Chemical analyse showed that manganese content in ore is 12.67 %. In first experiments, after hydrometallurgical treatment with concentrated sulphuric acid in period of 5 hours on temperature 80 °C, content of manganese in leaching solution was 174.3 mg. Sample has 2 g. In 2 g of ore there is 253.4 mg of manganese. Yield of the preliminary leaching experiments is 68.8 %.
