铅渣中提取硫工艺条件的研究

Lead Slag Extracted Sulfide Process Conditions

研究硫化钠浸取单质硫,探求铅渣中提取硫最佳工艺条件。结果表明:硫化钠浸取单质硫最佳工艺条件是液固比为3∶1,Na2S溶液浓度140g/l,硫化钠用量为理论量120%,浸出时间20分钟。

This paper studies the sodium sulfide leaching elemental sulfur, hunting lead residue extracted sulfur optimum process conditions. The results showed that： sodium sulfide leaching the optimum conditions for sulfur liquid to solid ratio 3 ＂ 1, the concentration of Na2S, 140g / I, sodium sulfide dosage of the theoretical amount of 120%, the leaching time of 20 minutes.
