 · An alternative production concept for calcium carbonate production is being developed that omits the need for fresh limestone and its calcination (Eloneva et al. 2009). This concept has the potential to reduce CO 2 emissions and simultaneously utilize steelmaking slag. In this process calcium is selectively extracted from steelmaking slag

Precipitated Calcium Carbonate (PCC) Minerals

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate such as limestone marble and chalk CaCO3. The calcium carbon and oxygen atoms can arrange themselves in three different ways to form three different calcium carbonate minerals.

How to make calcium carbonateclam mineral

 · Calcium carbonate can produce from the marble. You can make calcium carbonate from by crossing the CO2 from the calcium hydroxide. We can make this material by the mixing of the baking soda with acid boric. These are the ways that you can make calcium carbonate. Calcium carbonate is going to turn into the lime by losing CO2.
