Predicting the energy consumption of a grinding mill in real-time is of great importance for a mineral processing plant. Grinding is a critical stage in mineral processing and the number one in electrical energy consumption. The mills represent more than 70% of the total energy consumed in some units. The consumption prediction enables a balance in the production demand in a way that prefers the more economically viable moments. Thus, it is an effort toward sustainable mineral processing and low-cost operation. This paper presents the initial study to model the energy consumption of a grinding mill with an artificial neural network. The industrial data are provided by a copper mine plant in the north of Brazil.
