PEO CAS 25322-68-3 Selective Flocculant for Iron Ore and Coal Processing
Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer designed for selective flocculation in coal and iron ore beneficiation. Depending on different surface hydrophobicity of minerals, PEO selectively adsorbs on specific fine particles via hydrophobic interaction and hydrogen bonding, forming stable bridging flocs. It effectively separates coal or iron-bearing minerals from gangue such as quartz and clay, reduces fine particle entrainment during flotation an
Product Overview
Polyethylene Oxide PEO CAS 25322-68-3 is professional selective flocculant developed for iron ore and coal processing. Ordinary flocculants tend to cause non-selective aggregation of all particles, lowering separation effect. This PEO grade achieves selective flocculation based on mineral surface characteristics. It solves the difficult separation problem of ultrafine minerals, optimizes flotation indicators and promotes recycling of beneficiation wastewater.
Key Features
- CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
- Excellent selective adsorption property for coal and iron oxide minerals
- Realize selective flocculation, distinguish valuable minerals and gangue impurities
- Reduce fine gangue entrainment, raise concentrate grade and mineral recovery
- Nonionic structure, stable performance under various slurry pH and salinity
- Effective at low dosage, reduce overall beneficiation reagent cost
- Compatible with dispersants, collectors and other flotation additives
- Good settlement performance for tailings after separation, support water reuse
Main Applications
- Selective flocculant for fine coal washing and coal slurry separation
- Separation reagent for hematite, magnetite fine iron ore reverse flotation
- Functional polymer for removing clay and quartz gangue in mineral slurry
- Auxiliary additive for ultrafine mineral sorting and tailings solid-liquid separation
Usage Guidance
Gradually disperse PEO powder under gentle continuous stirring to avoid agglomeration and fish-eye pellets. Prepare dilute aqueous mother liquor before dosing into ore slurry. Complete laboratory flotation and sedimentation tests to confirm optimal addition amount. Avoid long-time high-shear mixing to prevent molecular chain fracture and performance decline.
Storage & Package
Seal packages tightly. Store in cool, dry and ventilated warehouse. Prevent moisture absorption, high temperature and direct sunlight. Standard package: 25kg kraft bag with inner PE liner. Shelf life: 12 months under properly sealed storage.
Service Support
Test samples available for mineral processing lab evaluation. Stable bulk supply. We provide TDS, COA and beneficiation process technical guidance. Welcome to inquire factory quotation.
