  • Flocculants ArrMaz

    Flocculants are used in the mining industry to treat the water used in mineral extraction and flotation processes. They help aggregate fine suspended particles to form larger flocs so that the solids can more easily be separated from the water. Flocculants are used to clean flotation process water to reduce reagent consumption and improve recovery.
