Increasing metal recovery from Incineration Bottom Ash requires a balanced recovery strategy rather than relying on a single sorting machine.

A high-efficiency IBA recovery system should focus on three key principles:

IBA composition varies significantly between different waste incineration plants. Equipment selection should be based on:

· Metal content

· Particle size distribution

· Moisture level

· Target product quality

This ensures each separation technology works under suitable conditions.

No single machine can recover all metal fractions from IBA.

An effective system usually combines:

· Magnetic separation for ferrous metals

· Eddy current separation for aluminum and other non-ferrous metals

· Additional fine recovery methods for small valuable particles

The combination of different technologies improves overall recovery efficiency.

Higher recovery rates depend on the performance of the complete recycling system, including:

· Stable feeding

· Proper screening

· Effective separation sequence

· Tailings monitoring and secondary recovery
