Standard Test Methods for Manganese in Iron Ores
This test method is intended to be used for compliance with compositional specifications for manganese content in iron ores, concentrates, and agglomerates. It is assumed that all who use these procedures will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices must be followed such as those described in Guide E 882.
1.1 These test methods cover the determination of manganese in iron ores, concentrates, and agglomerates. The following two test methods are included:
1.2 Test Method A covers the determination of manganese in the concentration range from 2.5 to 15.0 %. Test Method B covers the determination of manganese in the concentration range of 0.01 to 5.00 %. The lower limit for this test method is set at 50 % relative error for the lowest grade material tested in the interlaboratory study in accordance with Practice E 1601.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement 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.
