Sammanfattning

Carbon storage by mineralisation (CSM) is an option for CO2 emissions mitigation that has been under intensive study at Abo Akademi (AA), Finland. Magnesium from silicate rocks is extracted with recoverable ammonium salts at 250-500 degrees C. The extracted elements are separated by selective precipitation and Mg is subsequently carbonated in a pressurised fluidised bed. This work studies the applicability of the process for co-extraction of Ni, Cu, Fe and Mg from nickel ore and nickel mine waste rock (overburden). The rock samples were collected from the Hitura Nickel mine, Finland. The results show that it is possible to co-extract the listed elements and integrate CSM (by the AA process) with steelmaking and Ni production industries.
