摘要
用8-羟基喹啉、黄原酸钾、十六烷基三甲基溴化铵、磷酸三丁酯、柠檬酸5种物质作浸取助剂,考察了助剂作用下超声辅助浸取法从电解锰渣中提取锰的工艺条件。实验结果表明:用1%(质量分数)柠檬酸作浸取助剂,在固液比(g/mL)为1∶4、酸矿比(mL/g)为0.3∶1、浸取温度为70℃的条件下,超声浸取15min,锰浸出率平均可达57.28%,是加热酸浸法锰浸出率的2.72倍,是无助剂超声辅助浸取法锰浸出率的1.52倍。
The process conditions for extraction of manganese from electrolytic manganese residue by ultrasonic-assisted leaching with additive were investigated using 8-hydroxyquinoline, potassium xanthate, cetyl trimethyl ammonium bromide, tributyl phosphate and citric acid as leaching additives. The experimental results show that under the conditions of using 1% (mass fraction) lemon acid as leaching additive, ratio of solid to liquid (g/mL) 1:4, ratio of acid to ore (mL/g) 0.3 : 1, leaching temperature 70 ℃ and ultrasonic leaching time 15 min, the average leaching rate of manganese can reach 57.28%, which is 2.72 times that by common heating-acide leaching and 1.52 times that by ultrasonic-assisted leaching without leaching additive.
