以8-羟基奎宁、原磺酸酯、十六烷基三甲基溴化铵、磷酸三丁酯、柠檬酸为浸取助剂,对普通浸取法和超声浸取法从锰渣中回收锰进行考查,对助剂类型和用量、固液比、浸取温度、浸取时间和酸渣比对锰浸出率的影响进行了探讨。结果表明:以质量百分比浓度为1%的柠檬酸为浸取助剂,当固体的质量与液体体积比为1:4(g/mL)、酸的体积与锰渣质量比为0.3:1(mL/g)、在60℃温度下浸取120min,锰渣中锰浸出率为55.6%。相同条件下,超声浸取15min,锰浸出率为55.4%。超声助剂浸取法锰浸出率是普通无助剂浸取法的2.69倍,是无助剂超声浸取法的1.5倍。对于相同的浸出率,超声助剂浸取法的浸取时间只有普通浸取法的1/8。
With 8-hydroxy quinine, the original sulfonate, cetyltrimethylammonium bromide, tributyl phosphate, citric acid as leaching aids, the ordinary leaching method and ultrasonic leaching manganese recovery from manganese slag The effects of the type and amount of additives, solid-liquid ratio, leaching temperature, leaching time and acid to slag ratio on the leaching rate of manganese were discussed. The results showed that the mass ratio of citric acid to leachate was 1: 4 (g / mL), the mass ratio of acid to manganese was 0.3: 1 mL / g), leaching at 60 ℃ for 120min, manganese leaching rate of 55.6% manganese. The same conditions, ultrasonic leaching 15min, manganese leaching rate was 55.4%. Ultrasonic Auxiliaries Leaching Manganese leaching rate is 2.69 times of normal non-ative leaching method, which is 1.5 times higher than non-aided ultrasonic leaching method. For the same leaching rate, the leaching time of ultrasonic auxiliaries leaching method is only 1/8 of the ordinary leaching method.
