dry process for copper ore refining

Dry Process Copper Ore Refining: Equipment and Solutions

The dry process for copper ore refining eliminates water usage, reducing environmental impact and operational costs. Key equipment includes crushers, mills, and air classifiers tailored for copper ore processing.

Core Equipment for Dry Copper Ore Processing

1. Jaw Crusher: Primary crushing of copper ore (≤1500mm) to ≤250mm
– Model: JC1200
– Capacity: 800-1200t/h
– Power: 200kW

2. Vertical Shaft Impact Crusher: For shaping and sand-making
– Feed size: ≤60mm
– Output: 0-5mm sand (adjustable)
– Throughput: 300-500t/h

3. High-Pressure Grinding Roll (HPGR): Energy-efficient fine grinding
– Roll diameter: 1.8m
– Capacity: 600t/h
– Power consumption: 4-6kWh/t

Frequently Asked Questions

Q1: What’s the moisture limit for dry processing?
A: Optimal performance requires <3% moisture content. Pre-drying may be needed for wet ores.

Q2: How to control dust in dry systems?
A: Integrated bag filters with 99.9% efficiency, plus mist spray systems at transfer points.
