Total Solution for Metal Separation from Incineration Bottom Ash (IBA)

Total Solution for Metal Separation from Incineration Bottom Ash (IBA) is designed to turn waste slag into revenue.

This solution utilizes a "Physical Separation" process to recover ferrous/non-ferrous metals (Iron, Copper, Aluminum) and precious metals (Gold, Silver) from waste-to-energy plant slag. It achieves Zero Landfill goals by turning the remaining slag into construction aggregates.

Step 1: Pre-treatment (Crushing & Screening)

Goal: Liberate metals from slag and classify by size.

• Screening: Trommel Screen removes large debris and classifies material.
• Crushing: Specialized Impact Crusher breaks down large clinkers to release encapsulated metals without flattening ductile metals (like aluminum caps).

Step 2: Metal Sorting (Core Recovery)

Goal: Separate Ferrous, Non-Ferrous, and Precious Metals.

• Magnetic Separation: Dry Magnetic Separators recover Iron (Fe) and Steel.
• Eddy Current Separation: Ejects non-ferrous metals like Aluminum (Al) and Copper (Cu).
• Gravity Separation: Uses Jig Machines and Shaking Tables to recover heavy precious metals (Gold, Silver) and Stainless Steel.

Step 3: Post-treatment (Slag Recycling)

Goal: Ensure zero discharge.

• Dewatering: Filter Press and Dewatering Screens dry the final sand.
• Water Treatment: Closed-circuit water system ensures no wastewater discharge.
• Product: Clean slag is sold for brick making or roadbed materials (GB/T25032-2010 Standard).

Proven Track Record

• Jiangsu (State-owned): 1000 tons/day project.
• China (Listed Co.): 1200 tons/day project.
• Vietnam (Large Enterprise): 1000 tons/day project.
• Advantage: Fast ROI (10-18 months) and stable metal revenue.

Q1: What metals can be recovered?

A: We recover Ferrous metals (Iron), Non-ferrous metals (Copper, Aluminum, Zinc, Stainless Steel), and Precious metals (trace Gold and Silver) using gravity separation.

Q2: What happens to the remaining slag?

A: After metal extraction, the clean slag meets construction standards (GB/T25032-2010). It is sold as raw material for brick making, cement admixture, or roadbed bedding, achieving 100% resource utilization.

Q3: Is the process environmentally friendly?

A: Yes. The entire process uses physical separation (no chemicals). We implement a closed-loop water system with filter presses and sedimentation tanks to ensure zero wastewater discharge.
