Carbonate represents about 4% of the Earth’s crust
Calcium carbonate (CaCO3) is a mineral with terrestrial origin formed during the sedimentation of marine organisms (crustaceans, corals, etc.) in ancient oceans. Calcium carbonate represents about 4% of the Earth’s crust (Aït-Kadi, Hébert, Bouzenad 2015), making it one of the most abundant minerals on Earth.
Calcium carbonate is mainly extracted in open pit quarries, via mechanical extraction or via explosive depending on the veins. It is an inexpensive product and therefore it does not travel much around the world.
Calcium carbonate is the main source of calcium for animals.
Calcium is necessary for the formation of their bones and teeth, which is essential for their growth, and for the proper functioning of animal metabolism (contraction of muscles, functioning of enzymes, heart rate, etc.). Calcium is also needed in dairy and lactating species (suckler and lactating dairy cows, suckler sows, etc.) for the production of milk, and in laying species for the formation of the eggshell.
Phosphea is a producer of calcium carbonate through its Billy quarry, with a production capacity of 200,000 tons per year. We produce high quality calcium cCarbonate, our demanding control ensuring a high calcium content, a stable and controlled particle size, low humidity, as well as low levels of heavy metals.
