贵州铝厂氧化铝生产拜耳法工艺要求进厂铝土矿A/S=8,波动范围±0.5;联合法工艺要求进厂铝土矿A/S=5.2,允许波动范围±0.2,三天内平均值合格率>80％。为了确保上述要求和指导采场钻孔以达到降低贫化损失的目的,贵州铝厂和北京矿冶研究总院达成了共同研究铝土矿中铝、硅快速分析课题的 Guizhou Aluminum Plant Bayer process alumina production requirements into the plant bauxite A / S = 8, the fluctuation range of ± 0.5; joint process requirements into the plant bauxite A / S = 5.2, allowing the fluctuation range of ± 0.2, the average within three days The pass rate of> 80%. In order to ensure the above requirements and guide the drilling of stope to reduce the loss of depletion, Guizhou Aluminum Plant and Beijing Mining and Metallurgical Research Institute reached a joint research project on the rapid analysis of aluminum and silicon in bauxite
