Azurite Extra class

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

The future of Azurite Extra class is that we use a 3 steps cleaning process: sorting of raw material, flotation process of raw ground powder, and final flotation process of fine powder.
