scope:

1.1 This test method covers the determination of silver in the range of 13 µg/g to 500 µg/g by acid dissolution of the silver and measurement by atomic absorption spectrometry. Copper concentrates are internationally traded within the following content ranges:

Element Unit Content 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 µg/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 µg/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 µg/g 18.0 to 8000
Sulfur % 10.0 to 36.0
Tin % 0.004 to 0.012
Zinc % 0.005 to 4.30

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
