Polyelectrolyte for mining, sand and gravel washing
Wash plants and mineral circuits produce large volumes of water loaded with clay and fines. A high-molecular-weight anionic polymer settles those fines fast, so water can be recycled and tailings thickened.
Sunfloc Anionic HQ for regular plant use, or Anionic MQ for smaller plants and trials. Confirm on your own sample with a free jar test.
Tailings and thickeners
Anionic polyacrylamide is the standard choice for concentrating tailings and running thickeners. Anionic HQ or Anionic MQ is the starting point.
Sand and gravel washing
Wash water from M-sand and gravel plants clears quickly with an anionic grade, letting the plant recycle water instead of drawing fresh.
Coal washing and slime
Coal washeries use anionic polymer for concentration, filtration and slime settling. Alumina red mud settling also uses anionic grades.
Dosing on the plant
Make up a dilute solution and add it where the slurry is gently mixed, ahead of the thickener feed well. Confirm the dose with a settling test on your slurry.
