摘要:
以冶炼厂水处理污泥为原料,对其进行除砷提铜研究.探索了采用硫酸熟化—催化氧化从污泥中提取铜的工艺条件,当污泥中硫酸量为1 t/t,氧化剂(CH80)量为0.01 t/t,在液固比为4∶1,常温条件下,以250 r/min搅拌3 h,铜的提取率为94%.调节浸出液pH为3.7~4.0后,利用固砷剂除砷固砷,砷去除率为98.54%,此时铜的损失为1.34%,除砷后的浸出液制成硫酸铜产品,铜的总收率在85%以上.
Abstract:
The water treatment sludge of smelter mill were used as materials to study the refinement of copper and the removal of arsenic.The exploration has adopted the acidcatalyzed oxidation craft to refine copper from the sludge. When the amount of sulfuric acid 1 t/t, the antionxidant(CH80)capacity of 0.01 t/t and liquidsolid ratio at 4∶1, the copper lixiviated efficiency is 94% with 250 r/min and stiring from 3 h at the nomal temperature.The copper lixiviated efficiency is 94%. Adjust the lixiviated liquid at pH 3.7~4.0, then utilized the fixation of arsenic to remove and fix arsenic. Arsenic removal efficiency is 98.54% when the efficiency of the loss of copper is 1.34%. The lixiviated liquid after the removal of arsenic has been made to CuSO4 products. Copper reclaimed efficiency more than is 85%.
