Stainless Steel Slag Sorting Treatment and Resource Utilization Solution

Stainless Steel Slag Sorting & Resource Utilization Solution turns industrial waste into high-value alloy and construction materials.

This solution recovers Nickel-Iron Alloy from smelting slag using Magnetic or Gravity Separation. It achieves a metal recovery rate of >90% and converts the remaining tailings into eco-friendly building materials, realizing a 100% resource utilization rate.

Solution A: Magnetic Separation (For Low-Nickel Slag)

Principle: Low-nickel alloys are magnetic.

• Crushing: Release alloy particles from slag.
• Magnetic Separation: Use Dry/Wet Magnetic Separators to capture magnetic alloy particles.
• Advantage: Simple process, low cost, high efficiency.

Solution B: Gravity Separation (For High-Nickel Slag)

Principle: High-nickel alloys are non-magnetic but heavy.

• Crushing & Screening: Classify material size.
• Jigging: Use Jig Machines for coarse alloy recovery.
• Shaking Table: Use Shaking Tables for fine alloy recovery based on density difference.
• Advantage: Recovers high-value non-magnetic alloys that magnetic separation misses.

After extracting the metal, the remaining slag is not waste. It is processed into high-value products:

• Construction Aggregates: Road base material, concrete aggregate.
• Green Building Materials: Raw material for non-fired bricks and permeable blocks.
• Cement Admixture: Fine slag powder used as a cement replacement.
• Environmental Impact: Reduces carbon emissions by ~0.8 tons per ton of slag used.

Q1: How much metal can be recovered?

A: With our optimized process, the recovery rate of Nickel-Iron alloy typically exceeds 90%, turning waste disposal costs into significant profit.

Q2: Is the process environmentally safe?

A: Yes. The process is purely physical (Magnetic/Gravity) and uses no chemicals. We use a closed-loop water system to ensure zero wastewater discharge and no secondary pollution.

Q3: Can you handle wet slag?

A: Yes. We can design wet processing lines (Jigs/Shaking Tables) which are ideal for wet slag as they eliminate dust issues common with dry processing.
