研究了柠檬酸对赤铁矿磨矿效率的影响，并分析了其作用机理。结果表明：在最优磨矿介质条件下，添加赤铁矿质量分数0．10％的柠檬酸与不添加相比，可使磨矿产品中－0．074 mm 的含量提高7．11％；柠檬酸在赤铁矿表面产生的物理吸附和化学吸附，具有降低磨矿矿浆的粘度、改变赤铁矿表面的电位、降低赤铁矿表面的硬度等作用，因而柠檬酸能提高赤铁矿的磨矿效率。
研究瞭檸檬痠對赤鐵礦磨礦效率的影響，併分析瞭其作用機理。結果錶明：在最優磨礦介質條件下，添加赤鐵礦質量分數0．10％的檸檬痠與不添加相比，可使磨礦產品中－0．074 mm 的含量提高7．11％；檸檬痠在赤鐵礦錶麵產生的物理吸附和化學吸附，具有降低磨礦礦漿的粘度、改變赤鐵礦錶麵的電位、降低赤鐵礦錶麵的硬度等作用，因而檸檬痠能提高赤鐵礦的磨礦效率。

In this paper,the effect of citric acid on the hematite was studied and the mechanism was ana-lyzed.The results indicated that under the condition of the optimal grinding medium,compared with the result without citric acid added,with citric acid added at the mass of 0.10% of the hematite,the content of-0.074 mm of grinding production was increased by 7.11%;physical adsorption and chemical adsorption which were on the surface of hematite produced by citric acid can reduce viscosity of grinding pulp,change surface potential of the hematite,and reduce the hardness on the surface of the hematite.Therefore citric acid can improve the grinding efficiency of the hematite.
