FAQS on calcium carbonate from limestone

Q: How is calcium carbonate produced from limestone?

A: Calcium carbonate is derived from limestone by heating it at high temperatures (calcination), which breaks down calcium carbonate (CaCO₃) into calcium oxide (CaO) and CO₂. The calcium oxide is then hydrated and treated with CO₂ to precipitate purified calcium carbonate.

Q: What are the industrial uses of carbonate calcium carbonate?

A: Carbonate calcium carbonate is widely used in paper manufacturing, plastics, paints, and construction materials. It also serves as a dietary supplement, food additive, and antacid due to its non-toxic and alkaline properties.

Q: What is the chemical process behind calcium carbonate from limestone?

A: Limestone (CaCO₃) undergoes thermal decomposition to produce calcium oxide (CaO) and CO₂. When CaO reacts with water, it forms calcium hydroxide, which is then carbonated with CO₂ to regenerate high-purity calcium carbonate.

Q: Is calcium carbonate extraction from limestone environmentally sustainable?

A: While limestone is abundant, its processing releases CO₂, contributing to greenhouse gases. Sustainable practices include carbon capture technologies and optimizing energy efficiency during calcination to reduce environmental impact.

Q: Are there byproducts when obtaining calcium carbonate carbonate from limestone?

A: Yes, calcination of limestone produces calcium oxide (quicklime) and CO₂ as primary byproducts. These can be repurposed—for example, quicklime is used in cement, while captured CO₂ aids in re-precipitating calcium carbonate.
