style=\"color:red\">铌</span>损失率大且只能生产含<span style=\"color:red\">铌</span>13 %～15 %<span style=\"color:red\">铌</span>铁的情况,提出包头<span style=\"color:red\">铌</span>资源选冶新思路:用CO-CO2混合气体选择性热还原含<span style=\"color:red\">铌</span>铁矿,90 %以上的铁矿物被还原为<span style=\"color:red\">金属</span>铁,<span style=\"color:red\">铌</span>矿物不被还原.磁选分离被还原的<span style=\"color:red\">金属</span>铁和其他矿物,得到含Nb2O5为6.91 %的含<span style=\"color:red\">铌</span>氧化物,其品位较原矿富集了4倍.然后用盐酸浸洗上述含<span style=\"color:red\">铌</span>氧化物,90 %以上的铁矿物、磷矿物以及CaO和MgO进入浸液,<span style=\"color:red\">铌</span>儿乎全部留在浸渣中,得到的浸渣含Nb2O5近30 %,Nb/Fe＝6,Nb/P＝12,此浸渣可用于冶炼符合工业标准的<span style=\"color:red\">铌</span>铁(含60 %～65 %Nb).","authors":[{"authorName":"陈宏","id":"882e0fa3-0e0e-4414-afd5-dbcf58aafb91","originalAuthorName":"陈宏"},{"authorName":"韩其勇","id":"ccaae70d-9d66-47a5-a899-7a400a9a4032","originalAuthorName":"韩其勇"},{"authorName":"魏寿昆","id":"89c546b2-1edd-4fa9-9ffb-2f61126207c5","originalAuthorName":"魏寿昆"},{"authorName":"胡志高","id":"1732ea93-630a-4038-af98-761222422c01","originalAuthorName":"胡志高"}],"doi":"","fpage":"13","id":"3a13fdae-6c10-4739-b36f-fdeddc8ece44","issue":"3","journal":{"abbrevTitle":"GT","coverImgSrc":"journal/img/cover/GT.jpg","id":"27","issnPpub":"0449-749X","publisherId":"GT","title":"钢铁"},"keywords":[{"id":"4040c857-79a6-416e-a789-461de4d4499b","keyword":"含<span
