BS 7312:1990

This standard BS 7312:1990 Methods of test for magnetite for use in coal preparation is classified in these ICS categories:

• 73.020 Mining and quarrying

This International Standard specifies methods for the sampling and testing of magnetite for use in coal preparation.

The test methods are intended primarily for the testing of milled magnetite, the largest particle size of which is usually less than 250 gm. However, the tests are also applicable to unmilled magnetite with an upper particle size limit of about 500 µm.

Sampling, moisture content, sample preparation, particle size distribution, total magnetics content, relative density, total iron content and iron(II) content.
