Recovery of Valuable Elements from Oxidized Manganese Ores by SO₂ Process in A Pachuca Tank

Based on the results in small floating cell and in a series of three round bottom flasks, the experiments on the leaching of oxidized manganese ore using SO₂ were carried out in an experimental pachuca tank. The tested datum well agree with ones obtained mentioned above. The average recovery of Mn, Co and Ni are 94.80%, 89.70% and 81.50% respectively. The SO₂ content in the waste gas lowers less than 0.01%, which is below the allowed standard of SO₂ content in the waste gas in China.
