Vietnam White limestones (CaCO3)
White limestones (CaCO3) in Vietnam have superior quality compared to the products supplied by other neighboring countries such as Malaysia, Thailand, Indonesia … Here, we have two main zones exploiting raw materials which are Nghe An and Yen Bai. On the other hand, with all our knowledge, we affirmed that materials in Yen Bai are better in quality and whiter than Nghe An. With the advantage of owning and cooperating with more than 20 mines in Yen Bai together with the leading powder stone factories in the country, we are confident that we can bring you the best white limestones and white limestone products in the market with the most reasonable price at the most super service:
