lime to form solid calcium carbonate (CaCO 3). This is centrifugally separated from the flue gas in a cyclone separator. The solid material is then fed into a second fluidised bed reactor, which is called a calciner (Fig. 4). The CO 2 is separated from the calcium carbonate by adding heat. This process is known as calcination and is

How to Extract Calcium From Limestone Ores | Sciencing

Apr 24, 2017· Limestone is a naturally occurring mineral high in calcium carbonate, or CaCO3. It's possible to extract pure calcium from calcium carbonate through a multi-stage process requiring special equipment. Pure calcium reacts very quickly with the oxygen in the air, so you must store it in a non-reactive atmosphere, such as in a vacuum container.
