钒磷铁矿提钒
extraction of vanadium from the bear vanadium phosphosiderite
和94%。fantintiekuang tifan钒磷铁矿提钒(extraetion of vanadium frombear vanadium phosphosiderite)以含钒磷铁矿为原料制取五氧化二钒的帆提取方法。主要包括钠化焙烧和湿法漫出两道作业。直接用作提饥原料的是含饥磷铁。 含钒磷铁是饥磷铁矿电炉生产单质磷和磷肥的副产品。钒磷铁矿分布在美国爱达荷、蒙大拿、怀俄明、犹他等州,含Pz05 24%~32%、V:O。0.267%~0.625%和少量的铬、镍和钥等。美国克尔麦吉(Kerr-MeGee)化学公司所用的含钒磷铁含饥3.26%~5 .2%、磷24.7%~26.6%、铁59.9%一68.5%、铬3.4%一5.7%、镍。.84%~1%。先将含钒磷铁磨至粒度小于。.42mm,配入1.4倍纯碱和。.1倍的食盐在回转窑中于1043~lo63K温度下焙烧,钒便转变成水溶性的钠盐。熔烧块在加热到沸腾的水中浸出,钒、铬、磷均溶入浸出液。浸出浆液经过滤处理。滤液冷却结晶析出磷酸钠晶体,用离心机分离。晶体中如仍含有钒和铬,可用水重溶后再结晶分离,直到获得合格的磷酸钠(NaaPO;)晶体产品。若Na3PO‘结晶母液含磷高于0. 989/L时则要加入CaclZ,使其生成磷酸钙沉淀,然后水解回收钒。随后往母液中加入硝酸铅,沉淀出铬酸铅。此工艺的钒、铬和磷的回收率分别为85%、65%
