Calcium Carbonate
& Micronized Powders.

Mineral powders obtained from crushing and the recovery of quarry by-products, always above 95% calcium carbonate.

From by-product to value

Nothing is wasted,
everything is ground.

Processing fractions not suited for sale as blocks or crushed stone are recovered, crushed, and micronized at our plant, yielding a calcium carbonate powder with consistent grain size and a CaCO3 content always above 95%.

The raw material remains the same stone from the Perlato Royal basin: only the grinding grade changes, calibrated to the final use.
