High-molecular-weight polyacrylamide flocculant, PolyDADMAC cationic coagulant, and aluminum sulfate for clarifying mine process water, tailings, and produced water.
Flocculants and coagulants are water-treatment chemicals that remove suspended solids from process water, mineral tailings, and produced water so the clarified stream can be reinjected, discharged, or recycled. Coagulants neutralize the surface charge that holds fine particles apart; flocculants then bridge the destabilized particles into settleable flocs. The two are dosed in sequence, coagulant first. Jar-test the program before scaling it to a thickener or clarifier.
High-molecular-weight polyacrylamide (PAM) is the workhorse flocculant, supplied in anionic, cationic, and nonionic charge variants matched to the solids being treated. Charge density is the lever: a cationic grade suits organic-rich produced water, an anionic grade suits mineral tailings. The trade-off is real. Overdosing PAM restabilizes the suspension and blinds filters, so the lowest effective dose usually outperforms a heavy one.
PolyDADMAC is a lower-molecular-weight cationic coagulant used where charge neutralization is needed without the bulk of an inorganic salt. Aluminum sulfate (alum) remains the low-cost inorganic coagulant for high-turbidity feeds, though it adds sulfate and shifts pH downward. Match the program to your solids loading and discharge specification rather than to unit price alone.
