| Ore Grade | Copper Content (%) | Impurities | Moisture Content (%) | Appearance | Applications |
|---|---|---|---|---|---|
| High-Grade Ore | 20-30% | Minimal impurities | 0.5-1.5% | Reddish, dense ore | Electrical wiring, electronics production |
| Medium-Grade Ore | 10-20% | Trace impurities (iron, sulfur) | 1-2% | Uniform texture, earthy red | Industrial machinery, alloy production |
| Low-Grade Ore | 5-10% | Moderate impurities (iron, clay) | 2-3% | Coarse, darker red-brown | Secondary smelting, bulk industrial uses |
| Oxide Copper Ore | 1-5% | Iron oxide, trace silica | 3-5% | Porous, lighter color | Chemical processes, secondary copper extraction |
