摘　　要：利用白生料各矿物和煤表面物化性质的差异，建立了一种通过分离测定黑生料中煤的重量，进而得到黑生料的含煤的实验方法．测定绝对误差在±0.3％内，标准偏差0.118％，具有快速、简便、准确的特点。A method to measure the weight of coal in black raw meal and the coal content in black raw meal is found based on the different physical and chemical properties at the suiface of each mineral components and in white are meal and coal. The absolute deviation is less than 0.3% and the standard deviation is 0.118%. The method is fast, simple and accurate.
