Product Advantages
1. Slow Tailings Sedimentation and Turbid Overflow
Ordinary flocculants form small flocs with slow sedimentation speed, and suspended solids (SS) in overflow exceed standards, making reuse or discharge impossible.
Because we adopt high molecular weight (12–20 million) + moderate branched structure, large and dense flocs (diameter ≥3 mm) are formed, and sedimentation speed increases by 30–50%.
Your customers:
① Tailings water reuse rate increases from 60% to over 85%, saving thousands in water costs daily;
② Overflow SS decreases from 500 mg/L to below 50 mg/L, easily meeting standards. You help them save money, making them dependent on your product.
2. High Moisture Content of Filter Cake
Flocs are loose with strong water retention, resulting in filter cake moisture content above 35%, increasing transportation costs and tailings pond occupancy.
Because we optimize molecular chain flexibility, flocs have strong compression resistance and fast water release, resulting in filter cake moisture content ≤25% (5–10 percentage points lower than industry average).
Your customers:
① Sludge volume reduced by 15–20%, significantly lowering transportation and storage costs;
② Faster dry stacking, increasing processing capacity of the same equipment. Your product directly reduces their costs.
3. Fluctuating Performance Due to Ore Variability
Anionic PAM is highly affected by slurry pH and ore surface charge, causing performance fluctuations when ore types change.
Because nonionic polymers carry no charge and are not affected by slurry pH (4–10) or ore type, performance remains stable across different ores and slurry batches.
Your customers' operators do not need to frequently adjust chemicals, and you receive significantly fewer technical inquiries. Your time is valuable-saving it increases profit.
4. Slow Dissolution and Pipeline Blockage
Ordinary particles dissolve incompletely, forming "fish eyes" that block dosing pipelines and filter cloth, requiring frequent maintenance.
Because we adopt microporous rapid-dissolution granulation technology, complete dissolution is achieved within 10–15 minutes under normal temperature stirring, without fish eyes or blockage.
Your customers:
① Eliminate pre-dissolution tank investment;
② Reduce maintenance frequency by 70%;
③ Improve operator satisfaction. Your product naturally gains a good reputation.
5. Difficulty in Treating High-Concentration Slurry
When slurry concentration exceeds 20%, ordinary flocculants disperse unevenly and flocs break easily.
Because we adopt shear-resistant molecular structure design, efficient flocculation is maintained even under high concentration and high shear conditions.
Your customers can increase feed concentration, improving processing capacity by 20% with the same equipment. Helping customers expand capacity ensures repeat business.
6. Unstable Batch Quality
Competitor products have large molecular weight fluctuations, requiring frequent adjustments in concentration and flow rate.
Because we use DCS fully automated continuous polymerization + real-time viscosity monitoring, molecular weight deviation is controlled within ±3%.
Your customers can directly prepare solutions according to standard concentration, saving time and chemicals, while you reduce hidden after-sales support costs.
As a nonionic flocculant for tailings thickening and dewatering, this product shows particularly outstanding performance in improving sedimentation efficiency and reducing filter cake moisture content.

Product Process / Technical Strength
Core process steps:
- Raw material purification: Acrylamide monomer is purified through ion exchange resin towers and activated carbon adsorption towers to remove metal ions and inhibitors, achieving purity above 99.9%.
- Low-temperature composite initiation: Polymerization at -5°C results in higher molecular weight (up to 20 million+) and narrower distribution (PDI <1.6).
- Precise post-hydrolysis control: Hydrolysis degree ≤5%, maintaining nonionic characteristics and avoiding charge interference.
- Gel cutting and microporous granulation: Unique microporous technology allows rapid water penetration.
- Low-temperature fluidized bed drying: Prevents thermal degradation and preserves molecular chain integrity.
- Screening, homogenization, and automatic packaging: Automatic packaging lines with 25 kg moisture-proof bags, optional aluminum foil lining or bulk bags.

A: Yes, by improving efficiency to reduce dosage.
Q4: Do you support sample testing?
A: Yes, small-scale testing is recommended first.
Q5: Can it be customized?
A: Yes, parameters can be adjusted according to ore type and process.
Q6: What are the storage requirements?
A: Keep dry, moisture-proof, and avoid high temperatures.
Q7: What is the difference between nonionic PAM and anionic PAM in mining? How to recommend?
A: In simple terms, anionic PAM is suitable for positively charged mineral systems (such as iron ore), while nonionic PAM is suitable for systems with complex surface charges or large pH fluctuations (such as mixed ores, phosphate ore, gold ore, and coal washing). If unsure, we provide free sample testing for selection.
Q8: Will it degrade in tailings?
A: Our product maintains ≥95% viscosity retention within 24 hours in normal tailings slurry. For long-term recycling systems (such as closed-loop coal washing water), we offer high-stability models.
