The basic process of minerals’ mechanical preparation, including coal, is a beneficiation process which has a decisive impact on quantitative-and-qualitative parameters of commercial products. At present the products of the MBE-CMT, Allmineral and Tenova companies have big market shares as regards foreign water pulsatory jigs, as well as ITG KOMAG on the local Polish market. New implementations of jigs, developed at the KOMAG Institute of Mining Technology, for beneficiation of coking coal and steam coal in collaboration with Carbo-Eco Ltd. and Fugor Ltd. companies, were realized in 2019. Technical and technological parameters of new devices are described in the article. Supply systems of feed are presented as well as the method of collecting tailings and middlings. New design solutions, applied in modernized preparation plants, aimed at an improvement of jigs production capacity and efficiency are presented. In the case of each jig, after its activation and conducted adjusting processes, exact tests of a beneficiation efficiency were performed and their results are presented in the tabular form. Basic beneficiation accuracy indicators and parameters of products’ separation as well as balances of products are given. The test results, obtained from newly activated jigs, are discussed.
