Pure mineral stone
from the heart of Nghe An
Long Anh manufactures coated and uncoated CaCO₃ powder, slab stone, cut-to-size tile and decorative stone — serving plastics, paint, paper, construction, and global export markets.
Five core product lines
Tuned to each end use — from ultra-fine plastics filler to large decorative slab.
Uncoated CaCO₃ powder
Dry-ground GCC with high whiteness in multiple particle sizes — for paint, putty, adhesives, animal-feed additives and masterbatch.
