摘　　要：建立了磷、镁脱出的动力学模型 ,并得到硫酸脱出磷矿中氧化镁时磷、镁脱出的反应速率方程。同时应用计算机的三维图形对磷、镁脱出过程进行了表述。研究结果表明 :pH、反应温度、反应时间以及磷矿粒度对磷、镁脱出率有着不同的影响。The kinetic models for magnesium and phosphorus removals from ore were set up. The three-dimensional graphs and contour maps of magnesium and phosphorus removals from ore were pictured. The results showed that pH, reaction temperature, reaction time and particle size distributions of phosphate ore have different effect on the phosphorus removal and magnesium removal. The conclusion could be used for the industrial production of magnesium removal from phosphate ore with chemical way.
