Abstract
In an effort to lower atmospheric carbon dioxide (C02) levels, a number of sequestration
methods, including geological storage, ocean storage and mineral carbonation of CO2 have been
proposed for British Columbia. The selection of a suitable sink depends largely on the geology
available for a given region. A methodology for assessment of suitable raw material for the
mineral carbonation process has been proposed. The Tulameen ultramafic complex is selected as
a promising site for providing the raw feed for mineral C02 sequestration and representative
dunites have been collected and examined. Carbonation tests of these dunites took place at the
Albany Research Center in Oregon and C02 analyses in reaction products (up to 29.4 wt%)
suggest 48-56% conversion to magnesite and silica for the dunites, and 18% conversion for a
serpentinized dunite. Based on these results, one tonne of Tulameen dunite could potentially
sequester up to 0.4 tomes of C02.
