| Abstract: | The reasons that bring abnormal phenomena of magnesium content determination in phosphate rock are analyzed by the experiment of improving measure precision of EGTA solution. In view of the sample phosphate rock with low calcium oxide, the usage range of EGTA solution should be pointed out for the measure precision of magnesium content. |
