有机胺浸取法从湿法炼锌铁渣中回收锌
Retrieving Zinc from Iron-Zinc Slag by Organic Amine Leaching Method
摘要:
为了对炼锌铁渣中锌回收利用,以有机胺为浸取剂,对含锌铁渣进行浸取实验,考察了有机胺种类和浓度、温度、固液比及反应时间对锌浸出率的影响。结果表明:三乙烯四胺水溶液对锌有较好的浸出效果,其浓度和液固比对浸取影响高度显著,浸取时间对结果有一定的影响,浸取温度对结果影响较小。在三乙烯四胺浓度0.8 mol/L、浸出温度60℃、固液比5 L/kg的条件下反应浸取2 h,锌的浸出率达99.75%。
Abstract:
In order to recover and utilize zinc from zinc smelting slag, the effects of the types and concentra-tion of organic amines, temperature, solid-liquid ratio and reaction time on the zinc leaching rate were investigated. The results showed that triethylenetetramine method exhibited good leaching efficiency, the consistence and liquid-solid ratio had a significant effect on the leaching, the leaching time had a certain influence on the results, and the leaching temperature had little effect on the results. When the total triethylenetetramine concentration was 0.8 mol/L, the leaching tem-perature was 60˚C, the liquid-solid ratio was 5 L/kg and the leaching time was 2 h, the extraction rate of zinc was 99.75%.
