IMPROVEMENTS IN OR RELATING TO THE CAPTURE OF CARBON DIOXIDE

摘要

A method for capturing carbon dioxide comprising the steps of extracting mineral ions from a mineral source material to a mineral solution by reaction with a first ammonium salt; reacting the mineral solution with a CO2 source to precipitate a carbonate of the mineral and to produce a second ammonium salt; and recovering the first ammonium salt from the second ammonium salt.
