Natural pigment- Azurite hight quality

Azurite is a natural blue basic copper carbonate. The color of a pigment depends largely on their size and surface structure. Our employees perform elutriation and flotation of the feedstock, which provides richer colors. Thus, we achieve two different shades from one mineral from bright blue to deep blue.
