1.1 These test methods cover the determination of gold in ore processing cyanide solutions within the following ranges:
Method
Application Range, μg/mL
Inductively Coupled Plasma Mass Spectrometry
0.001 to 0.500
Flame Atomic Absorption Spectrometry
0.300 to 10.0
Note 1: The lower limit for the Inductively Coupled Plasma Mass Spectrometry Method, 0.001 µg/mL, was set following the guidance of Practice E1601. The reproducibility Index, R, was calculated using the total standard deviation for the lowest concentration Youden pair solution.
1.1.1 These test methods may also be applied to cyanide leach solutions from metallurgical evaluation procedures.
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 The test methods appear in the following order:
Sections
9 - 16
17 - 24
