Flotation technology is one of the most effective methods for separating solids and liquids in modern industrial processing. By allowing fine particles to attach to air bubbles and rise to the surface, flotation helps improve product purity and remove unwanted solids. Hengfeng Polyacrylamide (PAM) plays a key supporting role in these systems, helping operators achieve better efficiency, higher recovery rates, and more stable performance.

How Hengfeng Polyacrylamide Supports Flotation Processes

1. Enhancing Particle Flocculation

Anionic, cationic, or nonionic PAM helps fine particles form larger, more stable flocs. This makes flotation easier by ensuring that valuable materials selectively float while impurities settle more quickly.

2. Improving Water Clarity and Recycling

Most flotation circuits rely on recycled process water. Hengfeng PAM helps remove suspended solids and reduces turbidity, ensuring clean water flows back into the system. Better water quality improves flotation performance and reduces chemical usage.

3. Speeding Up Sludge Thickening and Dewatering

After flotation, the remaining slurry or tailings must be thickened and dewatered. High-molecular-weight PAM greatly accelerates settling and improves filtration efficiency, helping reduce moisture and lower disposal costs.

4. Maintaining System Stability

Consistent floc formation and faster separation create a more stable flotation circuit with predictable results. This leads to higher throughput and better operational reliability.

Industries That Use Flotation Systems

Flotation is not limited to mineral processing—it is widely used across multiple sectors:

1. Mining and Mineral Processing

Flotation is essential for separating valuable ores such as:

Copper,Gold,Lead and zinc,Phosphate,Fluorite,Barite,Coal

PAM enhances both the flotation stage and tailings management.

2. Non-Metallic Mineral Refining

Industries processing industrial minerals also rely on flotation, including:

Kaolin clay,Silica sand,Feldspar,Graphite,Talc

These applications require precise control of fine particles, making PAM vital.

3. Municipal and Industrial Wastewater Treatment

Dissolved Air Flotation (DAF) units are widely used to remove oils, fats, suspended solids, and organic contaminants from:

Petrochemical wastewater,Food and beverage processing plants,Slaughterhouses and meat processing,Textile and dyeing wastewater,Automotive and metalworking factories,Municipal treatment plants,PAM improves both flotation separation and sludge dewatering.

4. Pulp and Paper Industry

Flotation is used for deinking, fiber recovery, and white-water clarification. PAM helps improve separation efficiency and reduce chemical consumption.

5. Oil & Gas and Petroleum Refining

DAF flotation systems treat produced water and oily effluent. Cationic PAM enhances oil removal and supports stable operation.

Hengfeng Polyacrylamide is a crucial processing aid in flotation systems, providing improved flocculation, higher separation efficiency, and better sludge management. Its versatility makes it valuable in mining, mineral refining, wastewater treatment, papermaking, and oil & gas industries. As demand for cleaner water and higher recovery rates increases, PAM will continue to play an essential role in optimizing flotation performance.
