摘要
本文主要论述了钨精矿用苛性钠加压浸出得钨酸钠溶液,再采用大孔树脂固定床离子交换法提取仲钨酸铵的工业生产实践结果。
This paper mainly presents the production results of ammonium paratungstate extraction using ion-exchange on the fixed bed by macroporous resin from the sodium tungstate solution obtained by leaching the tungsten concentrate under pressure with caustic soda. The comparison among three methods for preparation of ammonium paratungstate was made:traditional precipitation,solvent extraction and ion-exchange.
