For the obtained samples, complete elemental analysis was performed on the S8 Tiger Wave X-ray fluorescence spectrometer. In the course of the experiment, the dependence of the content of ballast silicon (Si) and aluminum (Al) substances was revealed depending on the extraction stages, the purification method, and the drying method. As a result of the research, the optimum technological regime was chosen, observance of which of the Shilajit will be the minimum content of ballast substances.
