Product Introduction

Tailings Performance Changes with Mineralogy and Process Water

Tailings contain a broad particle-size distribution. Ultrafine clay or altered minerals can settle slowly even when coarse solids drop rapidly. Recycled process water, hardness, salinity, and residual flotation reagents can also shift polymer response.

A successful thickener polymer must deliver rapid aggregate growth, clear overflow, and a controllable underflow without creating fragile floc that breaks in the feedwell or rake zone.

Blufloc APAM Emulsion

High-molecular-weight anionic polyacrylamide emulsion accelerates mineral tailings settling and supports process-water recovery.

Blufloc EA 6520 and EWA 7520 are screened by ore mineralogy, clay content, water chemistry, solids loading, and thickener duty.

Application Challenges

Where Tailings Thickener Performance Becomes Unstable

Particle-size distribution, mineral surfaces, dissolved ions, flotation reagents, feedwell energy, and rake-zone conditions all affect settling, clarification, and underflow control.

Slow Ultrafine Settling

Clay and altered mineral fines may remain suspended long after the coarse fraction has settled.

Cloudy Overflow

Fine solids in the overflow can limit process-water reuse and increase downstream treatment demand.

Variable Ore Blend

Changes in mineralogy, clay content, grind, and recycled-water chemistry can alter polymer adsorption.

Feedwell and Rake Shear

Excessive energy can damage growing floc, while poor distribution can leave polymer and solids unmixed.

Treatment Mechanism

How the PAM Emulsion Works

Very-high-molecular-weight APAM chains adsorb across mineral particles and form large aggregates. Anionic charge influences chain extension and interaction with mineral surfaces and dissolved ions. Feedwell energy must distribute the polymer without destroying the growing floc.

Step 1

Prepare and Distribute

Activate and dilute the selected emulsion, then distribute it evenly across the incoming tailings stream.

Step 2

Bridge Mineral Fines

Long APAM chains adsorb onto multiple mineral particles and build larger, faster-settling aggregates.

Step 3

Settle and Compact

Controlled feedwell energy preserves floc so clear overflow and stable mud-line compaction can develop.

Important: The grades below are starting candidates, not a fixed prescription. Final selection and dosage require representative laboratory and plant trials. Confirm carrier-specific preparation instructions on the current grade-specific TDS.

Recommended Grades

Recommended Blufloc Grades

Compare candidates at equal active polymer mass using fresh tailings at operating solids, temperature, water chemistry, and feedwell-like mixing conditions.

Grade	Base	Molecular Weight	Charge	Suggested Screening Role
EA 6520	Oil-based	Very High	High anionic	Primary candidate for demanding tailings thickening
EWA 7520	Water-based	Very High	Medium anionic	Water-based comparator for moderate charge and automatic dosing

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.

Product Advantages

Strong Ultrafine Bridging for Thickener Operation

Very-high molecular weight for ultrafine mineral bridging
Potential for faster settling and clearer overflow
Liquid dosing for continuous thickener operation
Oil-based and water-based formulation choices
Mine-water and ore-specific laboratory screening

Application Process

Test with Representative Tailings and Feedwell-Like Mixing

Collect Representative Tailings

Use fresh tailings at operating solids concentration and temperature rather than an aged or diluted convenience sample.

Record Ore and Water Conditions

Document ore blend, particle size, clay content, hardness, salinity, recycled water, and residual flotation reagents.

Screen Dose and Dilution

Prepare each carrier correctly and apply repeatable, feedwell-like distribution without excessive floc damage.

Measure the Full Response

Record settling rate, supernatant clarity, mud-line compaction, underflow behavior, and floc strength.

Pilot at Realistic Throughput

Validate the preferred candidate under realistic feed rate and hydraulic loading before changing the full-scale program.

Product Selection Guidance

Let Mineralogy and Water Chemistry Decide the Optimum

EA 6520 is the core high-anionic screen for difficult mineral fines. EWA 7520 can perform well where medium anionic charge and water-based handling suit the mineral system. Ore mineralogy, clay content, process water, reagents, and thickener duty matter more than the product label alone.

Compare Total Operating Cost

Neat-emulsion price per kilogram can be misleading. Compare on active polymer mass and include preparation efficiency, thickener throughput, overflow quality, underflow control, and downstream handling cost.

Troubleshooting

Fast Settlement Does Not Always Mean Clear Overflow

If the Overflow Remains Cloudy

The polymer may be creating mixed floc sizes, or fine solids may be bypassing effective contact in the feedwell. Check dilution, injection distribution, feedwell energy, and dose before simply increasing molecular-weight demand.

Also separate polymer limitations from hydraulic short-circuiting, ore-blend changes, recycled-water chemistry, air entrainment, and excessive floc breakage in transfer or rake zones.

Safe Handling

Storage and Handling

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.

Frequently Asked Questions

Mineral Tailings Thickening FAQ

How is mining polymer dose expressed?

It is commonly compared as polymer mass per ton of dry solids. The optimum must be determined with representative tailings and verified in the operating thickener.

Does one APAM grade work for every ore?

No. Mineralogy, clay content, particle size, water chemistry, flotation reagents, solids loading, and shear can all change adsorption and settling performance.

Why use an emulsion instead of powder?

Emulsion can support rapid continuous make-down and liquid dosing. Performance, activity, site handling, logistics, equipment requirements, and total cost should still be compared.

Can APAM improve process-water recovery?

Better settling and overflow clarity can support water recovery, subject to thickener capacity, process-water quality requirements, and stable downstream operation.

EA and EWA Screening

Match the APAM Grade to the Ore, Process Water, and Thickener Duty

Screen EA 6520 and EWA 7520 with fresh representative tailings, controlled carrier-specific preparation, and feedwell-like mixing. Confirm the preferred grade using settling rate, overflow clarity, underflow density, floc strength, operating stability, and total cost.
