Development of a process for producing high‐purity calcium

The process consists of two main reactions; extraction of calcium in the form of calcium ions from waste cement powder in a water slurry by pressurized CO 2 (typically at several MPa), and precipitation of calcium carbonate (CaCO 3) from the extracted solution by reduction of the CO 2 pressure.
