中文摘要: 研究了酸化转型 + N235 萃取工艺从含铼结晶母液中提取铼的试验,结果表明,结晶母液稀释至含铼 470mg/L,溶液酸度 150g/L,萃取相比 20∶1,反应温度 25℃,反应时间 10min,铼萃取率可达 98% 以上。
Abstract:The experiment of extracting rhenium from rhenium-containing crystallization mother liquor by acidification transformation+N235 extraction process was studied. The results showed that when the crystallization mother liquor was diluted to 470mg/ L containing rhenium, the acidity of the solution was 150g/L, the extraction ratio was 20∶1, the reaction temperature was 25℃, and the reaction time was 10min, the extraction rate of rhenium could reach over 98%.
