RESUMO

Based on 74 ore-processing plants and their energy meter's coordinates in Zaruma-Portovelo, we determined the energy consumption profiles for each ore-processing plant following the methodologies of Gonçalves (2016) and Cabezas (2016). In doing so, the total energy consumption in comminution processes was calculated. Data show a rising trend in energy consumption in ore processing in Zaruma-Portovelo. The data can be of immense use in designing sectoral reforms for transparency in the mining sector and developing cross-sectoral coordination between ARCOM and ARCONEL. The data can also help the state agencies in assessing the quantity of ore processed and preventing the leakage of revenue from the extractive sectors (Gaudry et al., 2020). Finally, the scientific community may benefit from this data, particularly those working on energy consumption, efficiency, and its forecasts in extractive sectors (Gaudry et al., 2020).
