摘要
Abstract
The leaching liquor of scheelite concentrate ,leached by hydrochloric acid‐phosphoric acid , was used to precipitate (N H +4 )3 [PW12 O40 ] ・ 9 .5H2 O by the two‐step method of ammonium chloride precipitation and dissolved by ammonia water .Under the test conditions ,Fe ,P and Mo in the dissolved liquor can be completely removed .The purification liquor is evaporated and crystallized ,then filtrated and dried ,the ammonium paratungstate ,(NH +4 )10 H2 W12 O42 ・ 4H2 O is obtained .关键词
