Polyamine for Mining Process Water and Tailings Clarification
Product Overview
Mine-water circuits combine ground ore, clays, dissolved ions and residual flotation reagents. Fine particles can remain stable even when a flocculant is present. Polyamine is used upstream to reduce particle charge, allowing the selected flocculant to work on a better-conditioned suspension.
Potential applications include tailings thickeners, pit-water clarification, plant runoff and process-water recovery. The chemistry must be screened against the specific ore and reagent package to avoid unintended effects on mineral recovery.
Application Advantages
- Targets fine mineral particles that resist direct flocculation.
- Can improve flocculant efficiency in a staged program.
- Supports clearer recycle water and reduced suspended-solids return.
- Available in several solids and viscosity grades for site handling needs.

Recommended Treatment Approach
Test fresh samples before mineralogy or oxidation changes. Compare polyamine plus PAM with the current program using identical solids concentration and dilution water. Measure settling rate, overflow turbidity, bed compaction and, where relevant, the impact of recycled water on flotation.
Dosage Optimization
Choose the lowest robust dose across multiple representative samples. A program that works on one shift but fails when clay loading changes is not ready for full-scale use.
Handling and Storage
Use corrosion-compatible metering equipment and prevent contamination between chemical tanks. If dilution is required, add product to clean water with moderate agitation and verify solution stability before continuous use. Keep containers sealed and follow the grade-specific SDS and TDS for personal protection, storage temperature and spill response.
Frequently Asked Questions
Is one polyamine grade suitable for all ores?
No. Surface charge, clay content, salinity and process reagents differ significantly between mines, so grade screening is required.
Will it affect flotation recovery?
It may if treated water or polymer reaches the flotation circuit. Test recycle-water effects and coordinate trials with the metallurgical team.
What data should be supplied?
Include ore type, solids concentration, particle-size information, water chemistry, current reagents, separation equipment and target overflow quality.
Information for Product Selection
For a useful sample recommendation, provide the industry and wastewater source, pH, temperature, turbidity or TSS, color or COD where relevant, current chemicals and doses, treatment flow, separator type, sludge issue and required outlet quality. Bluwat can then shortlist suitable BLU AM grades for comparative testing.
