Calcium Carbonate

Packing with PP weave bag


Our mine where the calcite to be mined is unique as its heavy metal content. One of our engineer who has been working for 40 years in calcium carbonate industry, said that he has never seen any calcium carbonate with so little heavy metal. So, our calcium carbonate is a great advantage to be sued for food and medicine industry. This is very important. Most of other mines, its plumbum content is high. So, when these high plumbum content of calcium carbonate to be a raw material used for food or medicine industries, it will produces a harmful products. So, the people who wants to calcium supplement, but in fact he is enriching plumbum!!! Please note, the heavy metals are impossible to be got rid of from calcium carbonate with technology in modern times, even in USA. Our edible and pharmaceutical calcium carbonate can be used as a base for creams, powders, cosmetics or teeth pastes, its quality is top and can be passed USP in USA and FCC in Europe, but our price is very competitive.
