Standard Practices for Extraction of Elements from Ores and Related Metallurgical Materials by Acid Digestion
1.1 These practices cover the digestion of ores and related metallurgical materials, such as mine soil, waste rock and tailings, for subsequent determination of acid-extractable contents of certain elements by such solution analytical techniques as atomic absorption spectrometry (AAS), atomic emission spectrometry (ICP-AES), (see Test Method D1976), and inductively coupled plasma mass spectrometry (ICP-MS) (see Test Method D5673).
1.2 The digestion practices appear in the following order:...
1.3 The values stated SI units are to be regarded as the standard. No other units of measurements are included in this standard.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 11.
