Recovery and carbonation of 100% of calcium in
2018-2-10 Precipitation of calcium carbonate. Precipitation was accomplished by mixing equal parts (25 mL each) of calcium-rich and sodium carbonate solutions. The moles of Na 2 CO 3 added were equal to half the moles of HCl. The mixture was stirred at 400 rpm for 30 min then filtered under vacuum to recover the PCC.
