NASIL^® sodium silicate is used in the process of separating ore from gangue by the flotation method. It acts as a coadjuvant in deflocculation, controlling and helping the separation of the ore, while preventing corrosion of the milling equipment.

The use of ALNA^® for treating effluents generated in mining activities, especially Acid Mine Drainage (AMD), solves many environmental problems. It causes the precipitation of ettringite by removing sulfates (SAVMIN and CESR process).
