Standard Test Methods for Determination of Iron in Iron Ores and Related Materials by Dichromate Titrimetry
ORDER

Scope

1.1 These test methods cover the determination of total iron in iron ores, concentrates, and agglomerates in the concentration range 30 to 95 % iron.

1.2 The test methods in this standard are contained in the sections indicated as follows:

Test Method A-Iron by the Hydrogen Sulfide Reduction Dichromate Titration Method (30 to 75 % Fe)

Test Method B-Iron by the Stannous Chloride Reduction Dichromate Titration Method (35 to 95 % Fe)

Test Method C-Iron by the Silver Reduction Dichromate Titration Method (35 to 95 % Fe)

1.3 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 hazards statements are given in Section 5 and in special "Warning" paragraphs throughout these test methods.

Significance and Use

The determination of the total iron content is the primary means for establishing the commercial value of iron ores used in international trade.

These test methods are intended as referee methods for the determination of iron in iron ores. It is assumed that all who use these methods 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.
