中文摘要：

精确稳定的选矿生产过程数据可以用来流程考察、流程模拟、过程优化控制、生产考核、质量检验和决策管理;文章基于实际的选矿流程的矿物固体产率平衡、元素平衡、粒级产率平衡、粒级元素平衡约束，给出了选矿流程的数据校正模型，并采用鲁棒最小二乘法对实际选矿过程数据进行了数据校正；选矿过程校正后的数据满足物料平衡和元素平衡要求，给生产提供了正确的指导，可使生产流程在最佳工艺参数下运行。

英文摘要：

The accurate data of mineral processing can be used for process investigations, process simulation, optimization of process control, production assessment, testing and quality management and decision--making. This paper based on mineral solid yield balance. element balance, size fraction yield balance and size fraction element yield balance in constrained condition of mineral processing, gives the data reconciliation model of mineral processing. An example concerning actual mineral processing by robust least square was presented. After data reconciliation. The data met the demands of mass balance and elements balance, which provides correct guidance for the production, and enable the production process run under the optimum operating parameters.
