摘　　要：分析了东北某地硼矿石中硼镁铁矿物质组成 ,发现Fe(Ⅱ )可作为硼镁铁矿的特征性成份 ,且其含量与矿物的纯度成正相关。因而采用测定FeO含量并以求得的换算系数间接计算硼矿石中硼镁铁矿含量的化学物相分析方法。该方法操作简便、快速 ,相对误差小于 2 % ,用于选矿工艺研究中的分析测试 。It is found that Fe(Ⅱ) can be used as a characteristic component of ludwigite and its content has a positive correlation with its mineral's purity. Therefere, a chemical phase analysis method by which the FeO content is determinated and the ludwigite content in boron ores is proposed. The method is characterized by ease to operate, fast determination, below 2% relative error and good reproducibility of the measured results obtained in mineral processing technology study.
