The modifiers reagents create conditions in the pulp for optimal flotation and prepare the particles surface to adsorb the collectors and frothers. The main modifiers are the depressants, pH modifiers, defoamers and activators.We offer different innovative and safe chemical solutions that replace partial or totally the use of conventional modifiers.

Depressants of copper and pyrite: reagents that inhibit the hydrophobic properties of the particles having an inverse effect to that of the collectors. Our depressants are composed of thioglycolates, ethylene amines and carbamates.

Defoamers: compounds or polypropylene glycol that modify the foam

Dispersants and Rheology Modifiers: Acrylic surfactant polymers that help to disperse and stabilize the pulps with a high solids content, also improve the efficiency of the collectors.
