Based on a literature review, surface mining, comminution, their related sub-stages, and long-haul transportation have carefully been surveyed to elucidate the order of magnitude of the energy demand, the technical challenges posed by each operation, and the potential energy-savings achievable by applying opportune strategies. This work confirms the significant energy-saving opportunities in fine and ultrafine grinding (one of the most energy-consuming activities along the raw material supply chain) as underlined by previous studies, and, in addition, it focuses on limestone and olivine-rich rocks providing new outcomes, it analyses data from a climate change perspective and extends calculations and discussion to transportation.
