Cationic PAM for Mining Tailings Thickening
CAS Number: 69418-26-4
High-charge cationic polyacrylamide (40–70% cationicity) specifically formulated for flocculation of negatively charged mineral tailings slurries in thickener circuits. Ultra-high molecular weight (8–12 million Da) delivers rapid settling, clear overflow, and high-density underflow for efficient tailings management.
