Industrial grade flocculants optimized for mining, paper, municipal wastewater, and oil recovery.
Advanced chemical engineering principles behind high-efficiency solid-liquid separation.
Anionic Polyacrylamide (APAM) for mining is synthesized via modern bio-polymerization technology to achieve hyper-high molecular weights ranging from 8 Million to 25 Million Daltons. By copolymerizing acrylamide with acrylic acid monomers under strict controlled conditions, our APAM maintains structural molecular integrity, minimizing chain degradation. This high molecular weight provides extensive polymer chain length, critical for forming strong inter-particle bridges with mineral slurries.
In hydrometallurgy and mine tailings processing, suspended solids carry surface charges that prevent rapid natural settling. APAM acts through dual mechanisms: electrostatic charge neutralization and polymer bridging. When added to high-turbidity mineral suspensions, the negative carboxylate groups (-COO⁻) adsorb onto charged mineral surfaces, allowing the long polymer backbone to entangle multiple particles simultaneously. This creates massive, dense macro-flocs that settle at accelerated velocities.
Tailored polyacrylamide formulations designed for extreme mineral extraction environments.
During coal preparation, fine coal particles and clay form complex suspensions. Our high MW Anionic PAM rapidly clarifies thickener overflow water, achieving clear recycled process water while concentrating coal tailings for filter press dewatering. Results include reduced cake moisture and improved calorific values.
In bauxite refining, highly alkaline red mud slurries require specialized temperature-resistant and alkali-tolerant APAM polymers. Oubo’s high-hydrolysis APAM grades facilitate ultra-fast sedimentation rates in high-caustic environments (pH > 13), optimizing liquor clarification and alumina recovery.
For acid-leach and cyanide leach circuits (Counter-Current Decantation - CCD), APAM accelerates pregnant leach solution (PLS) clarification. Our polymers remain stable across wide pH ranges, protecting valuable dissolved metal complexes while maximizing thickener throughput.

Extending world-class polymer expertise across global industrial verticals.
Essential for municipal sewage and heavy industrial wastewater. APAM and CPAM flocculants settle suspended solids, clarify raw water, and dewater municipal sludge efficiently. This drastically reduces chemical dosage costs and minimizes sludge transportation volume.
Acts as wet-end retention aids, drainage accelerators, and dry-strength agents. Neutralizes anionic garbage, improves fine fiber retention rates, saves raw pulp consumption, and significantly enhances paper tensile strength.
Used for Enhanced Oil Recovery (EOR), profile control, and fracturing fluids. Serves as a rheology modifier and shale inhibitor in drilling fluids to decrease fluid loss, lubricate bits, and carry drill cuttings smoothly.
Food-grade polyacrylamide accelerates the settling of impurities during cane and beet juice clarification, delivering high-clarity syrup without leaving toxic chemical residues.
Functions as a textile warp sizing agent for smooth weaving, and as a primary flocculant for decoloring high-COD textile dyeing effluent.
Improves soil structure, prevents soil erosion from rainfall runoff, and increases water retention capacity in arid agricultural regions.
