Gangue and Tailing Reprocessing

-- Steady & Reliable Manufacturer --

Introduction

Turn mining waste into a profitable asset. Gangue (waste rock) and tailings (processed waste) often contain valuable residual minerals or can be re-processed into useful products for the construction industry. Our gangue and tailing reprocessing mills are designed to be the heart of a "waste-to-value" operation. By grinding these materials, you can either re-liberate valuable minerals for further extraction or produce a high-quality powder to be used as a supplementary cementitious material (SCM), filler, or soil conditioner, creating a new revenue stream and solving an environmental challenge.

Applications

  • Construction Materials: Grinding tailings (e.g., from iron, copper, gold mines) into a fine powder for use as an SCM in concrete, reducing cement usage.
  • Mineral Recovery: Re-grinding old tailings to liberate minerals that were not recoverable with older technologies, allowing for a second round of extraction.
  • Brick & Block Manufacturing: Using ground gangue as a raw material for producing environmentally friendly bricks and construction blocks.
  • Land Remediation: Grinding certain types of rock to create soil conditioners.

Advantages

  • Circular Economy Solution: Provides a clear path to convert an environmental liability (tailings dams) into a profitable, sustainable business.
  • High Energy Efficiency: Our vertical mills are ideal for this application, offering the lowest possible energy consumption for producing fine powder, which is critical for the economic viability of reprocessing.
  • Handles Variability: Tailings can be variable in composition and moisture. Our systems, especially vertical mills with integrated drying, are designed to handle these inconsistencies.
  • Adds Value: Transforms a zero-cost or negative-cost raw material into a valuable industrial product, offering excellent return on investment.

Payment & Shipping

For reprocessing projects, we understand the need for strong ROI calculations and can work with you on flexible payment solutions, including T/T and L/C. Our experienced logistics team manages the entire shipping process, from factory packaging to port delivery, ensuring your equipment arrives safely and on schedule.

Frequently Asked Questions

  • Q: Is it economically viable to re-grind old tailings?
  • A: It is increasingly viable. The value comes from two sources: recovering residual precious metals that were missed by older, less efficient technology, and/or creating a valuable construction material. With our energy-efficient mills, the operational cost is low, making the economics very attractive.
  • Q: What testing is required before we can start a tailings reprocessing project?
  • A: We strongly recommend a full analysis of your tailings. This includes chemical composition (to see what's in it), mineralogy (to understand how the minerals are locked), and grindability testing (to determine energy consumption). We can assist you with this testing process to design the optimal and most profitable reprocessing circuit for your specific material.
