▲ ▲ Sorting other metal minerals

Use DRX intelligent mineral sorting equipment to sort metal ores such as manganese ore, iron ore, copper ore, antimony ore, lead and zinc ore, etc., to remove impurities from metal ore raw materials and sort out metal ore products of different grades. It is also possible to select good ores that meet the metal ore grade requirements from previous metal mine tailings.

I. Metal ore raw material composition

The metals in metal ores usually exist in the form of metal oxides and metal sulfides, accompanied by carbonates, silicates and small amounts of other metal compounds.

II. Application Scenarios and Objectives

1. Applicable minerals: Manganese, iron, copper, antimony, lead, zinc, etc.
2. Processing targets: Mineral disposal, grade sorting, and metal ore recycle from tailings
3. Core objectives: Crushed and screened particles are then sorted for disposal or grade sorting using the DRX intelligent sorting equipment's dual-energy X-ray transmission imaging technology to achieve:
• Reduced mill feed, energy savings, and reduced chemical consumption
• Improved metal recycle, efficient resource utilization
• Environmentally friendly and safe alternative to heavy media sorting and manual sorting

III. Technical features of DRX equipment

• Identification technology: X-ray Dual-energy imaging + Intelligent image recognition
• Sorting method: Dry, high-speed sorting based on material density and elemental signature differences
• Processing capacity: Up to 200 tons/hour
• Identification accuracy: > 95%
• Applicable particle size range: 20–350 mm
• Control system: PLC + Industrial computer, supporting remote operation and data monitoring

IV. Process route

Plan A: Raw ore disposal
1. Stope → Crushing (150 mm)
2. Dry screening: Less than 20mm conventional grinding; 20mm～150mm enter DRX sorting DRX
3. DRX intelligent sorting: Select middlings; remove tailings

Plan B: Low-grade Stockpile Recycle
1. Stockpile → Crushing (150 mm)
2. Dry screening: Less than 20mm is discharged into real tailings; 20mm～150mm enter DRX sorting
3. DRX intelligent sorting: Eliminate true tailings; select middlings

Plan C: Middling classification
1. Middling → Crushing (80 mm)
2. Dry screening: Less than 20mm conventional grinding; 20mm-80 mm enter DRX sorting
3. DRX intelligent sorting: Separate into high-grade concentrate and low-grade ore

V. Case reference

VI. Conclusion

Softfox Technology's DRX intelligent mineral sorting equipment utilizes artificial intelligence (AI) recognition technology based on X-ray imaging to remove tailings from raw metal ore, sorting metal ore products by grade, and recovering high-quality ore that meets metal grade requirements from former tailings dumps. During the sorting process, particles are crushed to 150mm and then re-crushed to 80mm to improve sorting accuracy and increase metal ore recycle.
