1.1 These test methods cover the determination of total carbon and sulfur and acid-base characteristics in metal bearing ores and related materials such as leach residues, tailings, and waste rock within the following ranges:

Analyte

Application Range, %

Quantitative Range, %

Total Carbon

0 to 10

0.08 to 10

Total Sulfur

0 to 8.8

0.023 to 8.8


Note 1The test methods were tested over the following ranges:

Nitric Acid Loss Sulfur

-0.08 % to 4.19 %

Sodium Carbonate Insoluble Sulfur

0.007 % to 3.78 %


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 is 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:

 

Sections

Carbon and Sulfur, Total

10.1-10.9

Carbon and Sulfur, Residual from Pyrolysis

10.10-10.18

Carbon and Sulfur, Hydrochloric Acid Insoluble

10.19-10.27

Acid Neutralization Potential Acidity Titration

10.28-10.36

Acid Neutralization Potential Acidity Titration Low Range

10.37-10.46

Sulfur, Nitric Acid Insoluble

10.47-10.55

Sulfur, Sodium Carbonate Insoluble

10.56-10.64


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 6.
