The large-scale implementation of geochemical Carbon Dioxide Removal (CDR) approaches such as Enhanced Weathering (EW) and Ocean Liming (OL) will require the extraction and processing of large amounts of limestone and olivine-rich rocks. 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.
