Polyethylene Oxide MW 1,000,000 (PEO 1M, CAS 25322-68-3) is linear high-molecular-weight polyether polymer with excellent water solubility. In mineral pulp, long flexible molecular chains generate powerful bridging effect to capture ultrafine gangue and mineral particles, forming dense, fast-settling flocs. It improves slurry clarification efficiency, facilitates tailings filtration and water recycling. The nonionic structure keeps stable performance under various pulp pH environments. It serves

Product Detail

Product Overview

Polyethylene Oxide MW 1,000,000 (CAS 25322-68-3) is ultra-high molecular weight water-soluble PEO specially developed for mineral processing industry. Medium molecular weight PEO lacks sufficient bridging capacity for ultra-fine mineral particles; excessive high molecular weight grades easily lead to over-high slurry viscosity and poor fluidity. This 1M grade balances flocculation performance and solution rheology. The polymer adsorbs on fine mineral surfaces to build molecular bridges, gathering tiny suspended particles into stable flocs. It reduces fine particle entrainment during flotation, improves concentrate grade, accelerates tailings sedimentation and dewatering, and lowers suspended solid content in recycled mine water.

Key Features

Molecular Weight: 1,000,000, CAS 25322-68-3, white free-flowing fine powder
Outstanding water solubility, easy to prepare dilute flocculant aqueous solution
Strong bridging flocculation capacity for ultrafine mineral and gangue particles
Form compact flocs with fast settling speed, convenient solid-liquid separation
Stable performance within wide pH range of various mineral pulps
Good compatibility with conventional flotation collectors, inhibitors and coagulants
Low required dosage, effectively reduce chemical consumption and operation cost
Improve tailings dewatering efficiency and realize mine water recycling

Main Applications

Selective flocculant for coal washing slurry clarification and tailings treatment
Flocculation auxiliary for quartz ore, molybdenum ore, iron ore flotation separation
Settling agent for ultrafine tailings thickening and filter press dewatering
Solid-liquid separation additive for mineral processing wastewater recycling system

Usage Guidance

Slowly disperse PEO powder into continuously stirred clean water to prevent agglomeration, prepare 0.05%~0.1% dilute solution before adding into mineral pulp. Typical dosage: 30~200 g per ton dry ore. Adjust dosage according to particle fineness, pulp concentration and flotation test results. Complete laboratory sedimentation and flotation tests before on-site application.

Storage & Package

Seal packages tightly. Store in cool, dry and ventilated warehouse, avoid moisture absorption and direct sunlight. Standard package: 25kg kraft paper bag with inner PE liner. Shelf life: 12 months under proper storage.

Service Support
