本文介绍使用羟肟酸与非极性油类相配合,浮选泰美钽铌矿的细粒铌铁矿,使原矿由含Nb_2O_50.03％左右富集到精矿含Nb_2O_5 50％左右的工艺方法。探讨了细粒铌铁矿浮选过程中的几个主要因素及选别细粒铌铁矿的合理工艺流程。
This article describes the use of hydroxamic acid and non-polar oils, flotation fossil niobite niobium ore finer granite niobium, ore from about Nb_2O_50.03% enriched to concentrate containing Nb_2O_5 about 50% of the process . Several main factors in the flotation process of fine-grained niobite and the reasonable technological process of selecting fine-grained niobite were discussed.
