I. PAM's Role and Effectiveness in Mineral Processing Wastewater (PAM's Role and Effectiveness in Mineral Processing Wastewater)

Mineral processing wastewater is typically characterized by: large volume, high suspended solids (SS) content, presence of heavy metal ions and residual reagents, complex composition, and variable pH. PAM primarily performs the following functions to achieve reuse water use or compliance discharge standards: Mineral processing wastewater is typically characterized by: large volume, high suspended solids (SS) content, presence of heavy metal ions and residual reagents, complex composition, and variable pH.

Flocculation ku Sedimentation:

Mechanism: Active groups on the PAM molecular chain function through charge neutralization and bridging sweep flocculation.
