Silver Powder CAS：7440-22-4
Silver concentrate is the primary industrial raw material for silver production, obtained from silver-bearing ores through processes like crushing, grinding, and flotation. It typically appears as a gray-white to dark brown powder or small granules. As the starting point of the silver supply chain, it is the key intermediate product that connects mines to smelters, with about two-thirds of the world's silver resources derived from such associated ores.
1. Detailed Product Specifications

|---|---|---|---|---|
| Silver | Ag | g/t (ppm) | ≥ 3000 (Market Range: 3,000 - 6,000+) | The primary payable metal. Basis for valuation. |
| Gold | Au | g/t | 1 - 10 | A valuable credit when above threshold (e.g., ≥1 g/t). |
| Copper | Cu | % | 0.5 - 3.0 | A significant payable base metal at higher grades. |
| Lead | Pb | % | 0.5 - 4.0 | Affects concentrate classification and metallurgy. |
| Zinc | Zn | % | 1.0 - 12.0 | Affects concentrate classification and metallurgy. |
| Deleterious Elements | As, Bi, F, etc. | % | Strictly controlled per YS/T 433-2016 | Minimizes your smelting costs and environmental load. |
Physical Specifications
| Parameter | Specification | Details |
|---|---|---|
| Moisture Content | ≤ 12% | Settlement weight is calculated on a dry metric ton (DMT) basis. |
| Particle Size | -200 mesh (>75%) | Ensures optimal performance in standard smelting and leaching processes. |
| Appearance | Homogeneous grayish-black powder | Consistent physical quality for easy handling and feeding. |
Quality Assurance
Assay Methods: Silver and Gold content is determined by industry-standard Fire Assay. Base metals are analyzed via ICP-OES or AAS.
Certification: Each shipment is accompanied by a full Independent Assay Certificate from internationally recognized inspectors (e.g., SGS, AHK, CCIC).
