Washability Test Of Coal

  • 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.

    During the test, your sample is characterized and quantified as low-density clean coal, high-density reject or intermediate-density middlings. Our float/sink analysis can be performed on samples ranging in size from bulk washability samples (over 1 ton) to bench-scale size samples.

  • Standard Test Method for Determining the Washability

    5.1 Although the determination of the washability characteristics of coal is not an exact science, this washability test method can be used to investigate the cleaning characteristics of coarse- and fine-coal fractions. However, especially with the fine-coal fractions, this test method may not be applicable for low-rank coals for reasons explained in 1.2.

    2.5 COAL WASHABILITY Washability is a coal-cleaning jargon to designate amenability of a coal to gravity concentration. It is determined by sink-float testing as shown in Fig. 2.12. The test is performed by placing a sample of coal in progressively heavier specific gravity baths and scooping off the material that floats. This

    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
