Electronic Scrap Concentrates – precious metals content

Description

1. Product Overview

This product comprises high-grade electronic scrap concentrates, mechanically and thermally processed from end-of-life printed circuit boards (PCBs) and electronic components to maximize the recovery yield of gold, silver, palladium, and copper. It is primarily used as a secondary raw material for smelters, refiners, and integrated metal recovery facilities seeking an alternative to virgin mining. The key value proposition is a consistent, assay-certified feedstock delivering up to 30% lower processing costs per troy ounce compared to low-grade e-waste, while offering a strategically vital hedge against volatile primary metal markets. In an era of supply chain resilience and circular economy mandates, this concentrate enables industrial buyers to secure critical metals with verifiable traceability and lower carbon intensity.

2. Key Specifications & Technical Characteristics

  • Silver (Ag): 1,500 – 4,500 g/t

  • Palladium (Pd): 80 – 300 g/t

  • Copper (Cu): 18 – 28%

  • Tin (Sn), Lead (Pb), Nickel (Ni): Balance (each <5%)

  • Halogens (Cl, Br): <1.5% (low halogen variant available)

• Purity/Concentration Grade: Smelter‑ready concentrate; up to 98% metal liberation from base matrix.

• Physical Characteristics:

  • Form: Irregular granular powder + fine chips

  • Color: Dark grey to metallic black

  • Particle size: 95% passing 2 mm (10 mesh); fines <5% above 4 mm

  • Bulk density: 1.8 – 2.2 t/m³

• Packaging Options:

  • Sealed, anti-static big bags (1 MT net, palletized)

  • Steel drums with UN-certified liner (200 kg net)

  • Custom bulk bags for automated feeding systems

• Shelf Life: 24 months from production date when stored in dry, ambient conditions (<50% RH). No degradation of metal value.

3. Core Industrial Applications

• Primary Industries: Secondary copper smelting, precious metals refining, integrated metal recovery facilities, and specialty alloy manufacturing.

• Operational Use Cases:

  • Direct feeding to electric arc furnaces or copper flash smelters as a copper‑gold collector material.

  • Hydrometallurgical leach feed (cyanide or alternative lixiviants) for downstream metal separation.

  • Blending with primary concentrates to optimize smelter heat balance and slag chemistry.

• Performance Advantages over Alternatives:

  • vs. raw e-waste: 4x higher precious metal concentration → 60% reduction in slag volume and energy per kg of metal recovered.

  • vs. incinerated ash: lower halogen content minimizes corrosion of off‑gas systems.

  • vs. mine concentrate: comparably high Au/Cu ratio yields superior copper collector efficiency, reducing refining cycles.

• Commercial Benefit: Smelters using this concentrate report an average 18% higher furnace throughput due to improved thermal conductivity compared to shredded PCBs alone.

4. Competitive Advantages

• Quality Consistency: Every lot is triple‑assayed by ISO 17025 accredited labs (XRF + ICP‑MS); guaranteed metal value with ±3% tolerance – variance 50% lower than industry average.

• Supply Reliability: Multi‑source global feedstock agreements ensure monthly shipment capacity of 500+ MT. Production facilities with redundant processing lines guarantee 99.5% on‑time delivery.

• Logistics Capability: Export‑ready from three strategic hubs (Europe, Southeast Asia, North America). All shipments pre‑classified with HS code 7112.99 and accompanied by non‑hazardous waste certification per Basel Convention Annex IX, B1110.

• Price Competitiveness: Fixed‑fee refining charges (TC/RC) available via quarterly contracts; pricing formula linked directly to LBMA/LME spot metals minus a transparent treatment charge.

• Sustainability & Compliance: Full chain‑of‑custody from source to delivery. Carbon footprint per kg of gold is 1/10th that of mined gold. Compliant with EU Conflict Minerals Regulation and R2v3 certified.

• Technical Support: Dedicated metallurgist support for optimal furnace slag design and flux calculations. Pre‑shipment representative sampling protocols provided.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 MT (bulk order, single lot)

• Loading Capacity: 20 MT per standard 20‑foot dry container (palletized big bags); 26 MT per 40‑foot high cube container with floor‑loading configuration.
