Machine Learning and Deep Learning Methods in Mining
A step-by-step workflow on how to deal with real datasets, and how to find optimum models and final model selection is presented, which shows recurrent neural networks achieved the best forecasting metrics in the energy consumption prediction task. Semi-autogenous grinding mills play a critical role in the processing stage of many benefits, and save energy [3]. For the optimization research of a SAG mill, nowadays, there are mainly two categories of optimization strategies. One strategy is to use the discrete element method (DEM), combined with actual production data, to simulate and analyze en ergy change and particle movement inside a SAG mill.Operation Analysis of a SAG Mill under Different
