Intelligent Ore Sorting System
Core Technology
Nuctech’s Intelligent Ore Sorting System is based on X‑ray Transmission (XRT) imaging, supported by optional machine‑vision and multi‑sensor modules (XRF, neutron excitation, IR/microwave, electromagnetic analysis).
The system measures internal density/atomic‑number contrasts within individual ore particles and uses high‑pressure air jets for real‑time separation.
Key detection capabilities
- XRT: differentiates ore vs. waste by atomic number contrast
- XRF: elemental composition for precious/base metals
- Neutron excitation/transmission: lithium, gold, copper, antimony
- IR/microwave: thermal conductivity for Mn, Sn
- Visible light: surface texture for fluorite, Pb‑Zn
- EM analysis: conductivity/magnetism for Fe, Cu ores
This multi‑sensor flexibility allows deployment across coal, industrial minerals, and metal ores.
Product Category: Ore Sorting Units, Instruments, Coal, Metal Ore Mining, Cement & Non-metallic resources, Ash fusion Analyzer.
Features
Process Integration
The system is designed for pre‑concentration and waste rejection prior to grinding and flotation.
Typical integration points
- ROM → coarse crushing → screening → XRT sorting → mill feed
- Reduces the volume of waste entering the comminution circuit
- Improves downstream flotation performance
- Lowers energy consumption (grinding energy reduction is significant)
Coal applications
- Replaces heavy‑media separation, jigging, and manual sorting
- Reduces slime generation and eliminates media consumption
- Produces higher‑CV lump coal suitable for direct sale
Performance Characteristics
Sorting accuracy
- High‑precision detectors + AI algorithms
- Fast image processing and high‑speed ejection valves
- Typical sorting accuracy: >90–95% depending on ore type
Throughput
- Models available from 30 t/h to 330 t/h per machine
- Particle size ranges:
- 300–50 mm
- 100–25 mm
- 50–10 mm
- Mobile units available for field trials and remote operations
Energy & water
- Dry process — no water, no chemicals
- Unit power consumption is ~20% of traditional beneficiation
- Reduces mill energy by removing barren rock early
Environmental & Operational Design
- Fully enclosed, dust‑proof, waterproof, and explosion‑proof
- Operates from –40°C to +50°C
- Radiation shielding exceeds national standards
- Multiple emergency stops, multi‑camera monitoring
- Remote, local, and handheld operation modes
Radiation Safety
- X-ray technology is adopted to ensure that no ray remains after power failure
- X-ray shielding materials such as lead and steel are used to ensure the safety of system boundary
- the radiation safety standard of the system exceeds national standards to fully ensure the safety of staff
Application
Nuctech offers two types of ore sorting systems: a static (fixed‑installation) system designed for permanent processing plants, and a mobile system engineered for rapid deployment, field trials, and remote mining operations.
Mobile Sorting System
A fully integrated mobile XRT sorting unit for:
- Pilot trials
- Remote mine sites
- Short‑term campaigns
- Rapid deployment (≤3 days)
Includes sorter, control system, dust removal, and gas system in a single transportable module.
