Product Overview
PolyDADMAC, also known as Poly(dimethyl diallyl ammonium chloride) or PDADMAC, is a water-soluble cationic polymer with strong charge neutralization ability. It is widely used in mining wastewater treatment, mineral processing, sludge dewatering, and industrial clarification applications.
During gold ore processing, tailings wastewater usually contains fine mineral particles, clay, residual reagents, and suspended solids. These particles often remain stable in water due to surface charges, resulting in slow settling and poor thickening performance.
Bluwat PolyDADMAC flocculant helps destabilize suspended particles through charge neutralization and polymer adsorption. It promotes the formation of larger and stronger flocs, improving tailings thickening efficiency, reducing overflow turbidity, and enhancing water recycling.
Application in Gold Ore Tailings Thickening
Gold mining operations generate large volumes of tailings slurry after mineral extraction. Efficient tailings thickening is essential for:
PolyDADMAC is commonly used in gold ore tailings treatment systems for:
Key Benefits
Strong Charge Neutralization Performance
PolyDADMAC provides high cationic charge density, allowing effective neutralization of negatively charged mineral particles, clay, and fine tailings solids.
Improved Tailings Thickening Efficiency
The product promotes the formation of compact flocs, improving settling velocity and increasing thickener underflow solids concentration.
Cleaner Thickener Overflow Water
PolyDADMAC helps reduce suspended solids in overflow water, improving water quality for recycling into mineral processing operations.
Better Solid-Liquid Separation
By improving particle aggregation, PolyDADMAC supports more efficient filtration and dewatering processes.
Flexible Grade Selection
Different molecular weight and viscosity grades are available to match various gold ore types, slurry conditions, and treatment equipment.
Compatible with Mining Treatment Systems
PolyDADMAC can be used alone or combined with inorganic coagulants such as PAC depending on the characteristics of the tailings wastewater.
Working Principle in Gold Tailings Treatment
PolyDADMAC improves tailings thickening through:
- Neutralizing the negative surface charge of fine mineral particles.
- Reducing particle repulsion and destabilizing suspended solids.
- Creating larger flocs through polymer adsorption and bridging.
- Accelerating sedimentation in thickening tanks.
- Improving water separation from tailings solids.

Application Method
The optimum PolyDADMAC dosage depends on:
Before industrial application, jar testing and plant trials are recommended to determine the most suitable grade and dosage.
When used alone, PolyDADMAC should generally be diluted to 0.5–5% concentration based on solid content before dosing.
Proper mixing conditions should be maintained to ensure uniform chemical dispersion while avoiding excessive shear that may damage formed flocs.
