1.1 This test method covers the determination of silver in the range of 50 g/g to 1000 g/g by acid dissolution of the silver and measurement by atomic absorption spectrophotometry. Copper concentrates are internationally traded within the following concentration ranges:
| Element | Unit | Concentration Range | ||
| Aluminum | % | 0.05 | to | 2.50 |
| Antimony | % | 0.0001 | to | 4.50 |
| Arsenic | % | 0.01 | to | 0.50 |
| Barium | % | 0.003 | to | 0.10 |
| Bismuth | % | 0.001 | to | 0.16 |
| Cadmium | % | 0.0005 | to | 0.04 |
| Calcium | % | 0.05 | to | 4.00 |
| Carbon | % | 0.10 | to | 0.90 |
| Chlorine | % | 0.001 | to | 0.006 |
| Chromium | % | 0.0001 | to | 0.10 |
| Cobalt | % | 0.0005 | to | 0.20 |
| Copper | % | 10.0 | to | 44.0 |
| Fluorine | % | 0.001 | to | 0.10 |
| Gold | g/g | 1.40 | to | 100.0 |
| Iron | % | 12.0 | to | 30.0 |
| Lead | % | 0.01 | to | 1.40 |
| Magnesium | % | 0.02 | to | 2.00 |
| Manganese | % | 0.009 | to | 0.10 |
| Mercury | g/g | 0.05 | to | 50.0 |
| Molybdenum | % | 0.002 | to | 0.25 |
| Nickel | % | 0.0001 | to | 0.08 |
| Silicon | % | 0.40 | to | 20.0 |
| Silver | g/g | 18.0 | to | 8000 |
| Sulfur | % | 10.0 | to | 36.0 |
