[email protected]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.
to help you fully understand the traits of your coal, standard labs provides coal washability and float sink/study.From large coarse samples to small fine samples, we have the experienced personnel and state-of-the-art equipment to determine the limits of any mineral impurities in a coal .
