中文摘要: 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5 h、温度80 ℃、液固比4︰1。
Abstract: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 of 1.0, oxidant dosage of 50%, time of 5 h, temperature of 80 ℃, and L/S=4/1.
