Polyacrylamide Powder Supplier for Mining and Metallurgy Wastewater Treatment
Company Overview
Bluwat Chemicals is a professional manufacturer and global supplier of water treatment chemicals, including Polyacrylamide (PAM) powder for mining and metallurgy applications. With over 25 years of experience and exports to more than 80 countries, Bluwat provides high-quality flocculants with consistent performance, factory-direct supply, and technical support for mining and industrial wastewater treatment.
Product Introduction
Mining and metallurgical operations generate large volumes of tailings slurry and industrial wastewater containing ultrafine mineral particles, clay, silt, flotation residues, and suspended solids. Without effective flocculation, these particles settle slowly, resulting in poor water clarity, inefficient water recycling, and increased operational costs.
Bluwat Polyacrylamide Powder is a high molecular weight, water-soluble polymer designed for mining and metallurgy wastewater treatment. It promotes rapid flocculation, accelerates sedimentation, improves tailings thickening, and enhances overflow water clarity for process water recycling.
What Is Polyacrylamide Used for in Mining and Metallurgy?
Bluwat Polyacrylamide is widely used in various mining and metallurgical applications:
Tailings thickening
Slurry clarification
Thickener overflow clarification
Suspended solids removal
Process water recycling
Sludge dewatering support
Wastewater clarification in metallurgical plants
Tailings pond water treatment
Solid-liquid separation
Coal washing and mineral processing wastewater treatment
The product is available in anionic, cationic, and nonionic forms, suitable for a wide range of mining and metallurgical conditions.
Key Advantages of Bluwat Polyacrylamide Powder
Factory Direct Supply
Bluwat Chemicals offers factory-direct Polyacrylamide powder with consistent quality, reliable delivery, and competitive pricing.
High Molecular Weight Performance
High molecular weight PAM enables rapid flocculation, strong bridging, and dense floc formation for improved sedimentation and clarification.
Wide Application Scope
Suitable for mining, metallurgy, coal washing, sand washing, mineral processing, and industrial wastewater treatment.
Clearer Process Water
Improved flocculation reduces turbidity and suspended solids, supporting efficient water recycling.
Stable Thickener Operation
PAM improves tailings thickener performance, maintaining consistent underflow density and sedimentation efficiency.
Economical Operation
Effective at low dosage levels and dissolves rapidly, reducing chemical costs and sludge production.
Typical Applications
Tailings Thickening
Used to improve solid-liquid separation and underflow concentration in tailings thickeners.
Slurry Clarification
Enhances settling of fine mineral particles and suspended solids in mining and metallurgical wastewater.
Overflow Water Clarification
Reduces turbidity in thickener overflow for water recycling and process reuse.
Sludge Dewatering
Supports dewatering of tailings sludge, improving downstream handling efficiency.
Process Water Recycling
Clearer overflow water allows higher rates of process water recycling, reducing freshwater consumption.
Recommended Product Type
Bluwat provides a variety of Polyacrylamide grades for mining and metallurgy applications:
Product Type: Anionic/Cationic/Nonionic Polyacrylamide Powder
Appearance: Off-white granular powder
Molecular Weight: 5–25 million
Solid Content: Minimum 89%
Recommended Solution Concentration: 0.1–0.5%
Selection depends on tailings characteristics, wastewater type, and process requirements. Jar testing with actual wastewater is recommended to determine the optimal PAM grade and dosage.
How Polyacrylamide Works
Polyacrylamide works mainly via polymer bridging and adsorption:
- Long polymer chains adsorb onto fine particles in slurry and wastewater
- Particles are connected into larger, denser flocs
- Flocs settle quickly under gravity
- Overflow water becomes clearer
- Water recovery is improved
- Solid-liquid separation is enhanced
- Thickener operation is stabilized
Solution Preparation
- Prepare PAM solution at 0.1–0.5% concentration.
- Dissolve the powder slowly into clean water under agitation.
- Allow sufficient aging time (approx. 1 hour) for complete dissolution.
- Avoid high-speed agitation to prevent polymer chain damage.
- Dose into slurry pipelines, thickener feed wells, or clarification systems.
