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
Tin	%	0.004	to	0.012
Zinc	%	0.005	to	4.30
