    Abstract - (Show below) - (Hide below)

    Gives guidance on the apparatus and procedures for separation methods, based on differences in relative density, for determining the float and sink characteristics of raw coal and of products from coal preparation plants. Provides guidance on the presentation, of the results of such tests. Covers definitions, sampling, comprehensive plant efficiency tests, size analysis, pilot testing and presentation of results. Includes several appendices, tables and figures.
