铜生产过程中产出含铼中间尾料的浸出研究
|
摘要
针对某公司铜生产过程中产出的一种含铼中间尾料进行浸出试验,考察温度、终点pH、氧化剂用量、液固比及反应时间对物料中铼、铜、砷浸出率的影响。结果表明,在下述最佳浸出条件下铼、铜、砷的浸出率分别为81.72%、0.15%、94.19%:终点pH=1.0、氧化剂用量50%、时间5h、温度80℃、液固比4∶1。
Leaching of rhenium-bearing tailings in copper production was studied.Effects of temperature,end point pH value,oxidant dosage,L/S,and leaching time on leaching rate of rhenium,copper and arsenic were investigated.The results show that leaching rate of rhenium,copper and arsenic is 81.72%,0.15%and 94.19% respectively under the optimum leaching conditions including end point pH value of1.0,oxidant dosage of 50%,time of 5 h,temperature of 80℃,and L/S=4/1.
