Experimental Reseach on Leaching of Zinc From Electrode Material in Spent Alkaline Zn-Mn Battery
摘要
Abstract
The leaching of zinc from electrode materials of spent alkaline Zn-Mn battery using acids was not ideal ,and it was difficult to separate zinc from manganese in leaching solution .The leaching mechanism of zinc from electrode materials in ammonia and NH3 · H2 O-(NH4 )2 SO4 system respectively were investigated . The results showed that in ammonia system ,the leaching rate of zinc only reached 45% when the electrode materials were leached for 40 min at room temperature using 25% ammonia aqueous solution at V(liquid)∶m(solid) of 15∶1 .After adding (NH4)2SO4 into ammonia aqueous system ,the leaching rate of zinc reached 96% when the electrode materials were leached for 20 min at the conditions of room temperature ,(N H4 )2 SO4 mass concentration of 200 g/L and V (liquid)∶ m(solid) of 15∶1 using 25% ammonia aqueous solution .关键词
