PAMPolymer red mud settling flocculants are designed for alumina refineries using the Bayer process. Red mud contains very fine mineral solids in strongly alkaline liquor, and rapid separation is essential for efficient washing, liquor recovery and downstream filtration. High-charge anionic polymers bridge and entrap fine particles, promoting larger flocs and faster settling in primary thickeners and washing circuits.
An effective red mud program improves settling rate, underflow density and overflow clarity while reducing suspended solids carried into the pregnant liquor stream. Powder and emulsion grades can be considered according to make-down equipment, dosage control, slurry temperature, caustic concentration and required response time. Polymer performance is influenced by mineral composition, particle-size distribution, dilution, mixing energy and point of addition.
PAMPolymer supports product screening with representative red mud slurry and process liquor. Provide the refinery stage, solids concentration, temperature, caustic level, current settling curve and target overflow clarity. Graduated-cylinder tests and dynamic thickener trials help identify the grade and dosage that deliver reliable separation at the lowest practical treatment cost.
