SO₂法浸出锰矿石中的有价元素

摘要: 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SO₂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SO₂浓度可以降低到0.01%以下,符合排放标准。

Abstract: 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.
