Technical Features: In the context of global green mining transformation, the "Zero-Emission Mine Restoration System" is driving traditional mining industries towards environmentally friendly upgrades. This technology system achieves coordinated development of ecological restoration and resource utilization through three core modules:

1. Waste-Free Mining Technology System
Utilizing full-size ore sorting processes combined with X-ray intelligent sorting systems (XRT) and high-pressure roll crushing pre-treatment technology, this system reduces the cut-off grade for traditional mineral processing by 40%. Our independently developed bio-heap leaching-ion exchange joint process achieves an 82% recovery rate for low-grade copper ores below 0.3%, in conjunction with underground backfill mining methods, ensuring zero waste rock discharge during the mining process.

2. Tailings Resource Utilization System
Innovatively constructing a three-tier treatment chain of "physical separation-chemical purification-material preparation":
- Magnetic separation-flotation combined process to extract residual metals
- Acid leaching-precipitation method to recover rare earth elements
- Preparation of geopolymer concrete from tailings aggregate
Through gradient resource recovery, the overall utilization rate of tailings exceeds 95%, more than tripling traditional processes.

3. Intelligent Closed-Loop Ecological Restoration
Integrating satellite remote sensing monitoring and IoT sensor networks, we have established a dynamic restoration evaluation system with 12 key indicators. Using native plant-microorganism joint restoration technology along with nanomaterial soil amendments, vegetation coverage in restored areas can reach over 85% of the original state within three years.
This system has been validated and applied in multiple large non-ferrous metal mines, achieving:
- Annual reduction of tailings accumulation by 12 million tons
- Recovery of low-grade metal resources valued at over RMB 1.5 billion per year
- A 90% decrease in heavy metal content in groundwater in restored areas
- Zero wastewater discharge throughout the entire process
By deeply integrating resource value extraction and ecological restoration, this system pioneers a new model for mine lifecycle environmental management, providing a Chinese solution for global mining sustainability.
