Copper Ore Concentrate

Description

1. Product Overview

This Copper Ore Concentrate is a high-purity mineral product derived from multi-stage flotation and beneficiation of sulfide copper ores. It serves as the essential feedstock for copper smelters in the production of primary copper metal, cathode, and alloy intermediates. The key value proposition lies in its consistently high copper recovery rate, low penalty elements, and predictable smelting performance. Strategically, it offers buyers a secure, traceable supply chain solution in a volatile global metals market.

2. Key Specifications & Technical Characteristics

• Chemical composition: Cu 20–30% (basis), Fe 24–28%, S 28–32%, SiO₂ 6–12%

• Critical penalty elements (max): As <0.2%, Pb <0.1%, Zn <0.5%, Hg <0.001%, Cl <0.05%

• Moisture: 8–10% (as shipped)

• Physical form: Fine granular powder (80% passing 200 mesh)

• Appearance: Dark gray to black fine concentrate

• Bulk density: 1.8–2.2 t/m³

• Packaging options: 1.5 MT jumbo woven bags with PE liner, or loose bulk in shipping containers

• Shelf life: 12 months in dry, covered storage (no degradation risk if kept dry)

3. Core Industrial Applications

• Primary copper smelting: Direct feed for flash, reverberatory, or electric furnaces – achieves higher copper recovery per ton compared to low-grade ores.

• Electro-refining cathode production: Low impurity profile reduces downstream refining costs and minimizes anode slime formation.

• Alloy manufacturing: Used in producing brass, bronze, and copper-nickel alloys – predictable Fe and S levels improve melt consistency.

• Why better than alternatives: Uniform particle size and moisture content ensure stable furnace feed rates, reducing energy consumption and downtime versus variable mine-run material.

4. Competitive Advantages

• Quality consistency: Lot-by-lot XRF and AAS certification with independent third-party surveyor (SGS/Bureau Veritas) available.

• Supply reliability: Fixed monthly allocation of 5,000–20,000 WMT with back-to-back production planning.

• Logistics capability: Pre-cleaned containers and vessel-ready warehousing at origin port (turnaround <7 days from L/C confirmation).

• Price competitiveness: Direct ex-mine pricing absent trader markups; index-linked to LME grade A minus treatment charges (TC/RC).

• Sustainability benefit: Produced with dry-stack tailings and closed-water circuit – meets ISO 14001 and OECD due diligence standards.

• Technical support: Full assay sheets, smelter compatibility reports, and customs HS code advisory (2603.00) provided.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 500 metric tons (WMT – wet metric tons)

• BULK MOQ: 20 metric tons (for sample/trial shipment)

• Loading capacity: 22–25 WMT per standard 20ft dry container (jumbo bagged); 28–30 WMT per 20ft open-top container (loose bulk)
