摘要
用D36 3树脂吸附白钨精矿酸分解母液与洗水混合液中的钨 ,用 2 8mol/L氢氧化钠进行解吸 ,可获得含钨高的溶液。树脂用碱性次氯酸钠再生 ,盐酸转型后 ,重复使用性能稳定。该法简单经济 。
The recovery of tungsten from mixture solution of HCl digestion mother liquid and washing water of scheelite concentrate with D363 resin was investigated. High tungsten concent solution was obtained with 2.8 mol/L NaOH as strippant. Reusability of the resin was stable when regenerated with alkali NaClO and transformed by HCl. It is a sort of effective and economical method for recovery of tungsten.
