摘　　要：采用压片制样、X射线荧光光谱法测定浮选矿中磷、镁、铁、铝、硅、钙,选择了适合该矿种的测试条件,用经验系数和理论α系数法进行基体效应校正,各组分的标准偏差(SD,n=10)均小于0.04%,结果与化学法吻合。On sampling with compression method, the elements of P, Mg, Fe, Al, Si, Ca in floatation phosphate are determined by XRF under the suitable instrument parameters, with empirical coefficient and α coefficient for correction on matrix effect. Each standard deviation （SD, n=10） is less than 0.04%, the results by XRF method accord well with those by chemical method.
