To address the problem of low prediction accuracy and large noise data in gold leaching rate prediction, a high-efficiency intelligent prediction method was proposed. Combining the improved XGBoost and LightGBM models, a dynamic learning rate, regularization optimization, and Bayesian optimization algorithm were used to design an ensemble learning model for gold leaching rate prediction. The results show that the ensemble learning model has a significantly improved prediction accuracy compared to traditional single models, and its MSE is about 28.8% and 22.9% lower than XGBoost and LightGBM, respectively. The model has high stability in real production environments. The ensemble learning model can effectively improve the prediction accuracy of gold leaching rate and has strong practical application value.

针对金浸出率预测准确率不高及噪声数据较大的问题，提出了一种高效的智能预测方法。将改进的XGBoost和LightGBM模型相结合，并采用动态学习率、正则化优化和贝叶斯优化算法，设计了一个集成学习模型对金浸出率进行预测。结果表明：相较于传统单一模型，集成学习模型预测精度明显提升，其均方误差较XGBoost和LightGBM分别降低28.8%和22.9%左右，在真实生产环境中稳定性较高。该集成学习模型能够有效提高金浸出率的预测精度，具有较强的实际应用价值。
