Product Overview
PolyDADMAC, also known as PDADMAC or Poly(dimethyl diallyl ammonium chloride), is a liquid cationic polymer widely used in industrial wastewater treatment, mining water clarification, sludge dewatering, and mineral processing applications.
In copper and zinc mining operations, tailings water usually contains fine mineral particles, clay, metal-bearing solids, flotation residues, and suspended impurities. These particles are often stable in water and difficult to settle naturally, resulting in high turbidity, poor water recovery, and increased load on tailings ponds or clarification systems.
Bluwat PolyDADMAC Liquid provides strong cationic charge neutralization. It destabilizes negatively charged suspended solids and helps form larger, denser flocs. This improves tailings water clarification, thickener overflow quality, sludge dewatering performance, and recycled process water recovery.

Application in Copper and Zinc Mine Tailings Water Recovery
Copper and zinc processing plants require stable water recycling to reduce fresh water consumption, improve production efficiency, and meet environmental treatment requirements. PolyDADMAC Liquid can be applied in tailings treatment systems to improve solid-liquid separation and recover clearer water for reuse.
Typical application areas include:
Key Benefits
High Charge Density for Fast Particle Destabilization
PolyDADMAC provides strong positive charge, helping neutralize negatively charged copper and zinc tailings particles. This improves coagulation efficiency and accelerates the formation of settleable flocs.
Improved Tailings Water Recovery
By reducing suspended solids and turbidity, PolyDADMAC helps mining plants recover cleaner water from tailings systems and return it to the mineral processing circuit.
Better Thickener Overflow Quality
PolyDADMAC can improve particle aggregation before thickening, helping produce clearer overflow water and more stable underflow solids.
Enhanced Slurry Dewatering Performance
The product improves floc structure and supports more efficient water release during tailings dewatering, filter press operation, or sludge treatment.
Suitable for Complex Mining Wastewater
Copper and zinc mine water may contain clay, flotation chemicals, fine mineral solids, and variable pH conditions. PolyDADMAC offers flexible performance across different wastewater characteristics.
Works Alone or with Other Coagulants
PolyDADMAC can be used as a primary coagulant or combined with inorganic coagulants such as Polyaluminium Chloride to improve clarification performance.
Easy Liquid Handling
The liquid form is convenient for dilution, storage, and continuous dosing in mining wastewater treatment systems.
Working Principle
PolyDADMAC improves copper and zinc tailings water recovery through charge neutralization and floc formation.

Application Method
For copper and zinc mine tailings water recovery, PolyDADMAC should be selected according to the mineral composition, suspended solids concentration, tailings slurry density, pH value, and treatment equipment.
When used alone, PolyDADMAC is usually diluted to 0.5–5% concentration based on solid content before dosing.
The optimum dosage should be confirmed by jar testing and plant trial. The dosing point and mixing speed should be carefully controlled to ensure uniform dispersion of the chemical and avoid breaking formed flocs.
