摘　　要：讨论了灰色预测模型在原生矿浸出预测中的应用。基于灰色预测理论建立了GM(1,1)模型,并叙述了运用GM(1,1)模型进行预测的详细步骤,并以预测室内柱浸试验的浸出率为例进行了实际应用,最后用“残差大小检验法”和“均方差比值检验法”对预测结果进行了检验。结果表明:模型预测值与试验测试值吻合较好。The application of the grey forecasting model in predicting extraction rate of primary ore was discussed. The GM （ 1,1 ） model was established by using the gray forecasting theory and the detailed steps to carry out prediction by the model were described. Taking for example the extraction rate of a laboratory column leaching test, the actual application was carried out. The ＂residual test method＂ and the ＂mean variance ratio test method were used for checking. The results show that the forecasting value coincides with the experimental value.
