World data on (i) CO2-emission sites and (ii) ore deposits in mafic/ultramafic (M/UM) rock contexts have been crossed through a GIS (under ArcGIS) in order to identify sites of potential interest for implementing the ex-situ carbonation method. Applying relevant criteria, such as the nature and quantity of mining waste, volumes of CO2 emission, distance between mine and emission sites, and adding mining data from the literature, has led to a selection of eight potential ore deposits in an ultramafic rock context. These are located in Botswana, South Africa, China, Russia and Kazakhstan, and all lie within a 300 km radius of coal-fired industrial plants emitting >1Mt/year CO2. This approach is but a first level of reflective thinking that could be complemented by applying hydrographic, topographic, chemical and mineralogical, economic, and even political criteria. © 2011 Published by Elsevier Ltd. © 2011 Published by Elsevier Ltd.
