中文摘要: 铅阳极泥经过自然堆放氧化后，在5 mol/L硫酸介质中加入一定量的氯化钠（c(Cl-)=3mol/L）和氧化剂氯酸钠，液固比为5∶1，80 ℃控制电位氧化浸出4 h。结果表明，当铅阳极泥堆放氧化4天以上，氧化剂用量大于20%，电位400~500 mV时，铜、铋、锑、砷的浸出率均在99%以上，碲浸出率大于97%，金、银入液损失均小于1%，很好地实现了铜、铋、锑、砷、碲与金、银的分离。
Abstract:After natural stacking oxidation, lead anode slime was leached with potential controlled at 80 ℃ for four hours in medium of 5 mol/L sulfuric acid added with sodium chloride (c(Cl-)=3 mol/L) and oxidant of sodium chlorate with ratio of solid to liquid of 5∶1. The results show that the leaching rates of copper, bismuth, antimony and arsenic are all above 99%, the leaching rate of tellurium is above 97%, and the leaching rates of gold and silver are below 1% under the potential controlled leaching conditions including stacking duration of lead anode slime of over 4 days, oxidant dosage of >20%, and potential of 40~500 mV. Copper, bismuth, antimony, arsenic and tellurium are successfully separated from gold and silver.
