Standard Test Methods for Analysis of Metal Bearing Ores and Related Materials by Combustion Infrared Absorption Spectrometry
1.1 This test method covers the determination of total carbon and sulfur in metal bearing ores and related materials such as tailings and waste rock within the following ranges:
Note 1--The test methods were tested over the following ranges:Total Carbon- 0.01 to 5.87 %Total Sulfur- 0.0002 to 4.70 %Residual Carbon from Pyrolysis- 0.002 to 4.97 %Residual Sulfur from Pyrolysis- 0.014 to 1.54 %Pyrolysis Loss Sulfur- 0 to 4.42 %Hydrochloric Acid Insoluble Carbon- 0.025 to 0.47 %Hydrochloric Acid Loss Carbon- 0 to 5.78 %Hydrochloric Acid Insoluble Sulfur- 0.012 to 4.20 %.
1.2 The quantitative ranges for the partial decomposition test methods are dependent on the mineralogy of the samples being tested. The user of these test methods are advised to conduct an interlaboratory study in accordance with Practice E1601 on the test methods selected for use at a particular mining site, in order to establish the quantitative ranges for these test methods on a site-specific basis.
1.3 The test methods appear in the following order:
1.4 The values stated in SI units are to be regarded as standard.
1.5 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. Specific warning statements are given in Section 7.
