  • Standard Test Method for Determining the Washability

    1.1 This test method describes procedures for determining the washability characteristics of coarse-coal fractions and fine-coal fractions. Each sample being tested can have more than one coarse-coal size fraction and more than one fine-coal size fraction (see Annex A1).Each such size fraction has an upper size limit and a lower size limit, neither of which overlaps with the next larger nor

    The Australian Coal industry needs to find an alternative to the heavy organic liquids used to produce its coal washability analyses. Indeed, the existing Australian Standard for the Float and Sink analysis of coal is likely to be phased out over the next five years, and thus the matter needs to be urgently addressed to allow time to establish a new approach, with a new standard.

  • Float-Sink (Washability) Test, Coal Analysis, Kentucky

    In washability tests, coal samples are separated into float and sink fractions in liquids of increasing density. If a coal sample will be sent to a preparation plant that uses a fixed density for separating coal from rock and minerals, then a single float-sink test may be done on a sample at the fluid density used in the plant. The single float

  • Washability Monitor for Coal J&C Bachmann

  • Shaker Table Washability Curves

    Numerous methods of interpreting washability curves have been suggested by coal-washing engineers from time to time, and one method, which has become fairly well known in the last 8 or 10 years, is capable of giving a rather definite measure of the difficulty of washing any given coal to any desired ash content.

    The objective of the present study was to determine the washability curves for the coal from the lower seams of Candiota for power usage, evaluating their main characteristics in terms of both ash and total sulfur content, as well as the difficulty degree of their beneficiation through the NGM parameter. A comparative study between selective and simultaneous gravimetric beneficiation of such

  • Options for Washability Analysis of Coal—A Literature

    The existing Australian Standard for float and sink analysis of coal is likely to be phased out over the next five years because of its reliance on toxic organic liquids. Thus, the Australian coal industry needs to urgently find a suitable alternative, allowing enough time to establish a new approach with a new standard. It is possible that the industry in other countries will follow this lead.
