SO_2法浸出锰矿石中的有价元素

在小型浮选槽和3连圆底烧瓶浸出实验的基础上,在实验型空气搅拌浸出槽中进行了用SO_2浸出东湘桥地区氧化锰矿石2kg的实验。取得了良好的、与小型实验相符的实验结果。Mn、Co、Ni的平均浸出率分别为94.80％、89.70％和81.50％。尾气中SO_2浓度可以降低到0.01％以下,符合排放标准。

Recovery of Valuable Elements from Oxidized Manganese Ores by SO_2 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.
