ABOUT ARGONNE NATIONAL LABORATORY

The Pidgeon process has been described by Ramakrishnan and Koltun (2004b). This process consists of feeding crushed magnesium ore (dolomite) to a calcining process (1000–1300C) that produces dolime (CaO MgO). For each mole of magnesium, the calcination generates 2 moles of CO 2 (24 g Mg for 88 g CO 2). The calcined product is crushed and mixed
