The Manufacturing Process

HarvestingHarvesting:
Lithothamnion is harvested via a suction pipe descending from a vessel. The wet raw material is deposited in the ship’s storage tanks as the vessel moves slowly forward, with the harvested water returning to the sea. Being a natural harvest, Celtic Sea Minerals is governed by strict regulations to ensure no damage to the environment or surrounding sea-life.

Washing and Drying:
The Lithothamnion harvested from the seabed is first washed to remove sand and silica. It is then dried at 150°C for 16 minutes, ground to fine particle size and then packed or blended to customer specification.
