Aggregate fine coal, shale, and clay for faster settling, clearer recycled wash water, and more stable tailings thickening with oil-based EA 6520 and water-based EWA 7520.
Coal washing circuits accumulate ultrafine coal, shale, and clay. Poor settling reduces recycled-water quality, disrupts separation performance, and increases tailings inventory.
The preferred APAM depends on coal rank, clay mineralogy, process-water salinity, particle size, and whether the objective is clarified water, thickener underflow, or flotation-tailings capture.
Anionic PAM emulsion aggregates fine coal, clay, and mineral solids for faster settling and clearer recycled wash water.
Blufloc very-high-molecular-weight EA 6520 and EWA 7520 support continuous clarification and tailings thickening when selected with fresh, representative slurry.
Seam changes, fine clay, recycled-water chemistry, solids loading, and hydraulic shear can shift the optimum polymer grade, dose, dilution, and addition conditions.
Ultrafine coal and clay can remain dispersed and settle too slowly for efficient water recovery.
Residual fine solids can reduce recycled-water quality and disturb downstream separation performance.
Coal rank, ash, clay type, and particle-size distribution can alter adsorption and polymer demand.
High solids loading and short contact time can reduce distribution, floc growth, and settling performance.
APAM chains adsorb onto fine coal and mineral surfaces and bridge multiple particles into larger aggregates that settle under gravity. Very-high molecular weight supports long-range bridging, while the anionic degree must match particle surfaces, dissolved ions, and circuit conditions.
Activate and dilute the selected emulsion, then distribute it evenly through the fresh slurry.
Long APAM chains link fine coal, shale, clay, and mineral particles into larger aggregates.
Gentle floc growth supports clearer overflow and a denser, more controllable thickener underflow.
Compare candidates on equal active polymer mass using fresh, fully mixed coal slurry at realistic solids concentration, temperature, salinity, and hydraulic shear.
| Grade | Base | Molecular Weight | Charge | Suggested Screening Role |
|---|---|---|---|---|
| EA 6520 | Oil-based | Very High | High anionic | Strong candidate for coal tailings and clay-rich slurry |
| EWA 7520 | Water-based | Very High | Medium anionic | Water-based comparator for automatic wash-water treatment |
The product pages classify the cationic EC and EWC series as high molecular weight and the anionic EA and EWA grades as very high molecular weight. Confirm exact commercial specification limits, active content, viscosity, shelf life, and preparation instructions on the current grade-specific TDS and order specification.
Collect from the actual circuit and keep the sample fully mixed to prevent selective settling before testing.
Document seam, ash, clay, solids, particle size, pH, conductivity, salinity, and temperature.
Prepare each carrier correctly and apply repeatable mixing under the actual slurry concentration and shear range.
Record settling rate, interface clarity, compacted solids, floc strength, overflow color, and TSS.
Plant-test during representative production and confirm performance during normal loading and seam transitions.
EA 6520 is a strong first candidate for fine coal and clay-rich tailings. EWA 7520 should be compared where medium anionic charge or water-based dosing offers better process compatibility. Fresh slurry testing should guide the final choice.
Neat-emulsion price per kilogram can be misleading. Compare on active polymer mass and include activity, preparation efficiency, dose, equipment throughput, underflow quality, recycled-water impact, and downstream disposal cost.
Retest the grade and dose instead of only increasing polymer addition. Different clay minerals can change the preferred anionic charge, adsorption response, and dilution requirement.
Also check whether high shear, concentrated polymer feed, unstable make-down, uneven injection, or changing recycled-water salinity is preventing uniform distribution.
Keep the package sealed in a cool, dry, ventilated area. Protect it from direct sunlight, freezing, and excessive heat.
Follow the grade-specific TDS and SDS for shelf life, handling limits, and transport classification. Polymer spills can make floors extremely slippery and should be contained and cleaned promptly.
For coal slurry settling and wash-water recycling, Bluwat can screen adjacent PAM emulsion grades, review preparation and dosing conditions, and help define a plant-trial plan using agreed settling, overflow, underflow, recycled-water, and cost indicators.
Confirm the required grade specification and order documentation before production and shipment.
Shortlist products under realistic pH, temperature, solids, coal, clay, water chemistry, and shear.
Supply clear make-down, dilution, dosing, mixing, and scale-up recommendations for the selected grade.
Adjust charge level, dose, addition point, dilution, or mixing conditions using plant-trial data.
It can aggregate suspended solids, but whether the captured material is recovered product or tailings depends on circuit design, ash content, and product-quality requirements.
Particle surfaces, selective settling, oxidation, and slurry distribution can change during storage, making an old or partially settled sample less representative.
Yes. Dissolved ions can affect polymer-chain conformation, adsorption, and interactions with coal, shale, clay, and other mineral surfaces.
Not always. Seam, ash, particle-size distribution, and clay changes can require a different dose band, dilution, addition point, or grade re-screen.
Screen EA 6520 and EWA 7520 with fresh representative slurry, controlled carrier-specific preparation, and realistic mixing. Confirm the preferred grade using settling rate, overflow TSS, underflow solids, active polymer dose, recycled-water impact, operating stability, and total cost.
