FLOPAM AN 926 anionic polyacrylamide is a high-performance anionic polyacrylamide (APAM) flocculant manufactured by SNF. It is part of the FLOPAM AN series of water-soluble polymers designed for coagulation, flocculation, and solid-liquid separation applications. FLOPAM AN 926 is listed as a polyacrylamide product used for coagulation and flocculation applications in water treatment.

FLOPAM AN 926 contains negatively charged functional groups that provide strong interaction with suspended solids, mineral particles, and colloidal materials. Its primary working mechanisms are:

1. Adsorption – The polymer attaches to particle surfaces.
2. Polymer bridging – Long polymer chains connect multiple particles together.
3. Floc formation – Small particles become larger, stronger aggregates that settle faster.

Because of its anionic nature and high molecular weight characteristics, FLOPAM AN 926 anionic polyacrylamide is mainly applied in mining, mineral processing, wastewater clarification, sludge treatment, sand washing, and environmental protection industries.

1. Mining and Mineral Processing Applications

The largest application field of FLOPAM AN 926 anionic polyacrylamide is the mining industry.

Mining operations generate large quantities of fine suspended solids during:

• Crushing
• Grinding
• Flotation
• Beneficiation
• Concentration processes

These fine particles often remain suspended in water because of their small particle size and surface electrical properties.

FLOPAM AN 926 improves separation by creating larger mineral flocs.

Main mining applications:

• Tailings thickening
• Mineral concentrate thickening
• Slurry clarification
• Mine wastewater treatment
• Process water recycling

Benefits include:

• Faster settling of mineral solids
• Higher underflow density
• Clearer overflow water
• Improved water recovery
• Reduced tailings storage requirements

2. Tailings Thickening Application

Tailings management is one of the most important uses of FLOPAM AN 926 APAM.

After valuable minerals are extracted, the remaining tailings contain:

• Fine rock particles
• Clay minerals
• Silica
• Residual process chemicals
• Large amounts of water

Without treatment, these solids settle very slowly.

When FLOPAM AN 926 is added into the thickener feed, the polymer chains attach to mineral particles and form large flocs.

The results are:

Improved settling speed

Large flocs settle faster than individual fine particles.

Higher solids concentration

The settled underflow contains more solids and less water.

Better water recovery

Clarified overflow water can be recycled back into the plant.

This helps mining operations reduce:

• Fresh water consumption
• Tailings volume
• Operating costs

3. Iron Ore Processing Application

In iron ore beneficiation plants, fine particles are generated during grinding and concentration.

FLOPAM AN 926 is used in:

• Iron ore tailings settling
• Concentrate thickening
• Process water clarification

The polymer improves:

• Solid-liquid separation efficiency
• Thickener performance
• Filtration performance

Advantages:

• Faster settling of iron ore particles
• Reduced suspended solids in recycled water
• Improved plant productivity

Iron ore operations often select anionic polyacrylamide because mineral particles generally respond well to negatively charged polymers.

4. Coal Washing and Coal Preparation

Coal washing plants generate wastewater containing:

• Fine coal particles
• Clay
• Mineral impurities
• Suspended solids

These particles create highly turbid wastewater.

FLOPAM AN 926 anionic polyacrylamide helps:

• Aggregate fine coal particles
• Accelerate sedimentation
• Improve coal recovery
• Clarify recycled water

Applications include:

• Coal slurry thickening
• Clarifier treatment
• Fine coal recovery
• Water recycling systems

Benefits:

• Reduced wastewater discharge
• Lower water consumption
• Improved coal recovery efficiency

5. Industrial Wastewater Treatment

FLOPAM AN 926 is also widely used in industrial wastewater clarification.

Industries generating suspended solids include:

• Chemical plants
• Steel manufacturing
• Cement production
• Ceramic factories
• Paper mills
• Food processing facilities

The polymer helps remove:

• Suspended solids
• Mineral particles
• Metal hydroxides
• Colloidal materials

Treatment benefits:

• Lower turbidity
• Improved clarification
• Better sludge settling
• Improved filtration

In many wastewater systems, FLOPAM AN 926 is used after inorganic coagulants such as:

• Poly aluminum chloride (PAC)
• Aluminum sulfate
• Ferric chloride

The coagulant destabilizes particles, while the polymer creates larger flocs.

6. Sludge Thickening and Dewatering

Another important application of FLOPAM AN 926 anionic polyacrylamide is sludge treatment.

Some sludge streams contain high amounts of:

• Mineral solids
• Inorganic particles
• Metal hydroxides

These materials can be effectively conditioned with anionic polymers.

Applications include:

• Filter press systems
• Belt filter presses
• Centrifuges
• Gravity thickeners

The polymer improves:

• Sludge settling
• Filtration rate
• Cake solids concentration
• Water release

Advantages:

• Reduced sludge volume
• Lower disposal costs
• Improved equipment efficiency

7. Sand Washing and Aggregate Industry

Sand and gravel washing produces wastewater containing:

• Fine sand
• Clay particles
• Silica particles
• Suspended minerals

These fine particles make water cloudy and difficult to recycle.

FLOPAM AN 926 is used in:

• Sand washing plants
• Quarry wastewater treatment
• Aggregate recycling systems

Functions:

• Accelerate settling in settling ponds
• Improve water clarity
• Recover fine materials
• Reduce fresh water usage

Benefits:

• Cleaner recycled water

8. Alumina and Bauxite Processing

Anionic polyacrylamide products are widely used in alumina refining processes.

In the Bayer process, large amounts of red mud are generated.

Applications include:

• Red mud settling
• Clarification of sodium aluminate liquor
• CCD washing circuits
• Solid-liquid separation

FLOPAM AN 926 can help improve:

• Settling speed
• Liquor recovery
