摘要
实验研究了Zn S晶种对拜耳法中硫化钠脱锌技术的影响,证明了Zn S晶种可以提高硫化钠脱锌效率,考察了硫化钠浓度、反应温度、反应时间、Zn S晶种对除锌效果的影响,结果表明,在反应温度为60℃,反应时间为90min,硫化钠浓度为0.4g/L,Zn S晶种添加量为40mg/L的条件下可以将拜耳液中锌杂质脱除到15mg/L以下,达到国家标准。
The influence of ZnS seed on dezinclfication technology using Na2S in Bayer process was studied, it was proved that ZnS seed could improve the dezincification efficiency and Na2 S concentration, reaction temperature, reaction time, ZnS seed were investigated. The results showed that zinc impurities in Bayer liquid could be less than 15mg/L met the national standard when the condition was that the reaction temperature was 60℃, the reaction time was 90min, sodium sulfide concentration of 0.4g/L and ZnS seed of dosage 40mg/L.
