What is BS 7312 - Methods of test for magnetite for use in coal preparation about?

BS 7312 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 4m. However, the tests are also applicable to unmilled magnetite with an upper particle size limit of about 500 4m. Note: BS 7312 applies exclusively to the testing of magnetite and no attempt is made to recommend specific tests for the dense medium suspensions of which magnetite forms the solid phase.
