Breakthrough in Zinc Recovery: How Polyurethane Screens Are Transforming Global Zinc Processing

Break Gives Way to Innovation: Polyurethane Screens Set New Standard in Zinc Processing

As global zinc producers confront shrinking ore grades, higher processing costs, and increasing regulatory pressure, technological innovation has become essential for sustainable growth. Among the most impactful advances is the adoption of high-performance polyurethane screening systems.

Screening is no longer a passive operation — it is a core driver of recovery, efficiency, and profitability.

Evolving Challenges in Zinc Processing

• Processing of more complex ore bodies

• Higher throughput requirements with finer particle sizes

• Environmental compliance and water management pressure

• Market demand for concentrates exceeding 55% Zn purity

Critical Screening Functions in Zinc Production

Primary screening removes oversized material prior to grinding.
Intermediate screening stabilizes cyclone feed and enhances milling productivity.
Final concentrate screening guarantees precise sizing before filtration and transport.

Why Polyurethane is Redefining Screening Performance

Conventional steel screens deteriorate rapidly in zinc circuits due to corrosion, sulfide adhesion, and abrasion. Their service life often falls below four months, increasing downtime and operating costs.

Modern polyurethane screens deliver:

• Service life extended by 500–800%

• Exceptional resistance to acidic processing environments

• No iron contamination of zinc concentrate

• Stable performance under aggressive flotation conditions

• Major reductions in maintenance frequency and downtime
