【摘要】 大冶铁矿浮选产物之一的硫钴精矿中钴是以类质同象存在于黄铁矿中，其分布是不均匀的，因此，提高硫钴精矿钴品位难度较大，有用矿物粒度较细，其解离度也比较高，但部分有用矿物呈复杂的浸染交代结构彼此或与脉石嵌镶，故欲提高分离浮选作业指标则比较困难。更多还原

【Abstract】 In the flotation product of Daye iron mine, cobalt is dispersed as isomorphism in the pyrite, likewise, it is not homogeneous distribution. Therefore, it is difficult to increase the cobalt grade of S-Co concentrate. The valuable minerals size is fine, and its degree of liberation is high. but, partial valuable minerals each other or with gangue disseminate in form of impregnate metasomatic texture. So, it is not ready to improve the index of Cu-S flotation.更多还原
