CONTAINED IN VOL. 03.05, 2014 Defines the determination of silver corrections for fire assay of metal bearing ores, concentrates and related metallurgical materials using the spent slags and cupels from the fire assay process, by gravimetry and atomic absorption spectrophotometry.

1.1This practice covers the determination of silver corrections for fire assay of metal bearing ores, concentrates and related metallurgical materials using the spent slags and cupels from the fire assay process, by gravimetry and atomic absorption spectrophotometry.

1.2The test methods appear in the following order:

Sections

Gravimetric Method

10–11

Atomic Absorption Method

12–13


1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This standard does not purport to address all of the safety concerns, if any, associated with its use.
