|
Abstract:
本文研究了高铋铅阳极泥的浸出工艺；考察了浸出剂、浸出时间、浸出温度、液固体积质量比、浸出剂浓度、双氧水加入量对锑、铋浸出率的影响。结果表明：在液固比3:1，盐酸浓度为6 mol/L，反应温度30℃~50℃，双氧水加入量为375 kg/吨铅阳极泥的条件下，锑、铋浸出率均达95%以上，金、银几乎不浸出。
In this paper, the leaching process of high bismuth lead anode slime was studied. The effects of extractant, leaching time, leaching temperature, volume-to-mass ratio of liquid to solid, concentration of leaching agent and amount of hydrogen peroxide on the leaching rate of antimony and bismuth were investigated. The results show that under the conditions of liquid-solid ratio of 3:1, concentration of hydrochloric acid of 6 mol/L, reaction temperature of 30？C~50？C, addition of hydrogen peroxide of 375 kg/ton of high bismuth lead anode slime, the leaching rate of antimony and bismuth is more than 95%, and gold and silver are hardly leached.
