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 removensuspended solids from process water, mineral tailings, and produced water so thenclarified stream can be reinjected, discharged, or recycled. Coagulantsnneutralize the surface charge that holds fine particles apart; flocculants then bridgenthe destabilized particles into settleable flocs. The two are dosed in sequence,ncoagulant first. Jar-test the program before scaling it to a thickener or clarifier.
nnHigh-molecular-weight polyacrylamide (PAM) is the workhorse flocculant, supplied innanionic, cationic, and nonionic charge variants matched to the solids being treated.nCharge density is the lever: a cationic grade suits organic-rich produced water, annanionic grade suits mineral tailings. The trade-off is real. Overdosing PAMnrestabilizes the suspension and blinds filters, so the lowest effective dose usuallynoutperforms a heavy one.
nnPolyDADMAC is a lower-molecular-weight cationic coagulant used where chargenneutralization is needed without the bulk of an inorganic salt. Aluminum sulfate (alum)nremains the low-cost inorganic coagulant for high-turbidity feeds, though it addsnsulfate and shifts pH downward. Match the program to your solids loading and dischargenspecification rather than to unit price alone.
