| 摘 要： | 磷灰石晶体主要呈柱状、针状、集晶或散粒嵌布于铁矿石及脉石矿物中，粒度较小，难以分离，矿石中磷含量的高低对炼铁、炼钢都有较大影响。铁矿中磷的测定一般用磷钼酸铵容量法、铋磷钼蓝分光光度法等，文中对测定宁乡式高磷铁矿中磷的方法进行探讨。

| Abstract: | Apatite crystal mainly exists as columnar,acicular,aggregate crystalline or bulk grains inlaid in iron ore and gangue.The grain size is small and it is difficult to be separated.The phosphorus content in ore has a great effect on iron making and steel making.The measure methods of phosphorus in iron ore mainly use the ammonium phosphomolybdate volume method,the bisumth phosphomolybdenum blue spectrophotometric method.The measure method of the phosphorus in the Ningxiang type iron ore containing high phosphorus is discussed. |
