Abstract
The invention comprises a method of mineralization of carbon dioxide. The method comprises delivering hyaloclastite, a volcanic glass or pumice to a mill capable of reducing the particle size of the hyaloclastite, a volcanic glass or pumice; processing the hyaloclastite, a volcanic glass or pumice in the mill so that the processed hyaloclastite, a volcanic glass or pumice has a volume-based mean particle size of less than or equal to 40 μm; and exposing the hyaloclastite, a volcanic glass or pumice to carbon dioxide in gaseous, liquid or solid form during or after the particle reduction process. Optionally a carbon dioxide sorbent or carbonation enhancing agent is added to the hyaloclastite pozzolan or mineral during the grinding or post-grinding process and combined with carbon dioxide during grinding or post grinding.
