Tailings Re-Election Process and Resource Utilization Overall Solution

Tailings Re-election Process and Resource Utilization Solution turns waste into profit.

This comprehensive solution focuses on "Secondary Recovery + Eco-friendly Utilization". By re-processing tailings to extract residual valuable metals (Gold, Copper, Iron, etc.) and converting the remaining waste into construction materials, we help mines achieve 100% resource utilization and zero discharge.

1. Precious Metal Tailings (Gold/Silver)

• Gold Tailings: Use CIL (Carbon In Leach) or Flotation to recover residual gold. Iron is recovered via magnetic separation.
• Silver Tailings: Flotation or Leaching-Replacement process for refractory silver.

2. Non-Ferrous Tailings (Copper/Lead/Zinc/Tungsten)

• Copper/Lead/Zinc: Flotation is key to recover residual sulfides. Acid leaching extracts oxide copper.
• Tungsten: Centrifugal Concentrator + Shaking Table recovers fine tungsten slime.

3. Ferrous & Non-Metallic Tailings (Iron/Phosphate)

• Iron Tailings: High Gradient Magnetic Separation recovers fine iron.
• Phosphate/Graphite: Flotation separates valuable minerals from gangue like silica.

After extracting valuable metals, the remaining tailings are processed into commercial products:

• Mine Backfill: Filling underground voids to prevent subsidence.
• Construction Materials: Making bricks (non-fired), ceramic granules, or road base.
• Cement Raw Material: Tailings rich in silica/iron can be cement additives.
• Dry Stacking: Using Filter Press to dewater tailings for safe, small-footprint storage.

Project: 1 Million TPA Gold Tailings Plant

• Process: CIL for Gold + Magnetic Sep for Iron.
• Results: 71% Gold Recovery, 65% Iron Concentrate Grade.
• Utilization: 100% of final tailings used for new building materials.

Q1: Is tailings reprocessing profitable?

A: Yes. Since the mining and crushing costs (the most expensive parts) are already paid, recovering even low-grade minerals from tailings has a very low operating cost and high profit margin.

Q2: How do you handle environmental safety?

A: We use a closed-loop water system with >90% recycling. For gold tailings, we include a cyanide destruction system. Final dry stacking prevents dam failures and leakage.

Q3: Can you make bricks from any tailings?

A: Most silica-based tailings are suitable. We conduct a laboratory test to determine the chemical composition and strength to design the right "recipe" for brick or cement production.
