【摘要】 应用模式识别方法将难处理金矿焙烧预处理工艺中的第一段焙烧温度、气氛、时间和第二段焙烧温度及时间五元素形成的五维空间投影到各自的二维平面上，浸出残渣含金为目标函数，从二维投影图中可区分样本点的好坏，从边界条件可判别各因素的作用．利用人工神经网络程序对已知的实验数据点进行了预报，结果与实验值基本一致．更多还原

【Abstract】 The roasting pretreatment experiment parameters for refractory gold ores were analyzed with the patternrecognition. Based on the models the results of roasting experiment were predicted with the artificial network.The predicted value is in good accordance with the experimental results.更多还原
