Again to quote Shoemaker and Gould, "Increased production of the final product is often more easily and economically attained through expansion than by increased recovery." Planning for expansion is therefore a consideration in all but the shortest-lived operations. Even at mines

Some of the re-circulating CO2 has to replace air used in milling coal and transporting it to the burners. This stream, the primary recirculation, has to be dry enough to take up moisture from the coal feed and has to be preheated to 250-300C. Oxygen should not be added to this stream to minimize risk of fires and explosions in the mills.
