description: The given work is devoted to the study of the applicability of energy dispersive X-ray fluorescence analysis (ED XRF) to determine the ash content of coal concentrates at concentration plants. 1. Study of possible radiation instrumental methods for determining the ash content of coals and coal products. 2. Conducting tests to assess the applicability of the XRF method for determining the ash content of coal concentrates at concentration plants. 3. Processing of the results obtained and their comparison with laboratory data. Optimization of the method. The tests were carried out at the coal preparation plant Â«AbashevskayaÂ». Novokuznetsk city, where the ash content of coal samples was measured on the ED-XRF analyzer Â«X-Art Coal MÂ». According to the approved program and method of testing, were provided for measurement 2 sets of concentrates and 4 sets of samples for various enrichment methods, a total of 241 samples. Further on the territory of scientific-technical department JSC "Comita" Saint-Petersburg city, the optimization of the method was carried out based on the results obtained before and repeated tests of the analysis of ash content. The result of this work evaluated the applicability of X-ray fluorescence analysis method for determining coal ash content concentrates at the concentrator, optimized measurement method. The paper presents the achieved errors in the results of the analysis of ash content by the XRF method.
