ASTM E2941

Extraction of Elements from Ores and Related Metallurgical Materials by Acid Digestion

Applicability: ASTM E2941 applies to the acid digestion of ores and metallurgical materials, such as mine soil, waste rock, and tailings, to extract and determine the acid-soluble content of specific elements.

Purpose: ASTM E2941 is used for compositional analysis, compliance testing, and environmental monitoring, with the resulting solution then analyzed using techniques like ICP-AES or ICP-MS. The standard includes methods for both nitric acid and four-acid digestion.
