Describes the tracers used (iodide, lithium, chloride, chromium), the tracer measurement (principle, field measurement and laboratory measurements), environmental factors affecting tracers, techniques for tracer injection, sampling techniques, analysis and sources of error.

Describes the tracers used (fluorescein, rhodamine B, acid yellow 7, sulfo rhodamine B, pyranine, and rhodamine WT), the tracer measurement (principle, field measurement and laboratory measurements), environmental factors affecting tracers, techniques for tracer injection, sampling techniques, analysis and computation.

Specifies the test method, the instrumentation requirements, the measuring assessment method and the way to report the test result.

The method is based on drying of an air-dried test portion to constant mass in a laboratory oven at 105 °C to 110 °C, and measurement of the loss in mass. The determination is intended to be carried out simultaneously with that of other constituents of the same analytical sample, so that the contents of the other constituents can be calculated on the basis of the absolutely dry ore. Should be…
