Recovery of Valuable Elements from Oxidized Manganese Ores by SO2 Process in A Pachuca Tank
-
摘要: 在小型浮選槽和3連圓底燒瓶浸出實驗的基礎上,在實驗型空氣攪拌浸出槽中進行了用SO2浸出東湘橋地區氧化錳礦石2kg的實驗。取得了良好的、與小型實驗相符的實驗結果。Mn、Co、Ni的平均浸出率分別為94.80%、89.70%和81.50%。尾氣中SO2濃度可以降低到0.01%以下,符合排放標準。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.
