X-ray fluorescent separation process simulation

Features of X-ray fluorescent sorting of different types of mineral raw materials are associated with a number of factors, the separation results are a function of many variables and situations. To take into account the factors, it is necessary to create a simulation model of the sorting process. The model developed using the MATLAB software package for solving problems of technical calculations makes it possible to simulate the sorting process based on the principles of X-ray fluorescent separation, taking into account different types of the mineral phase distribution over the volume and surface of the lump and the separator measurement geometry. As a result of simulation modeling, separation curves were obtained. Its showing the tailings yield dependence on the valuable component mass fraction ratio in the separation tailings to the valuable component weighted average mass fraction for sorted classes of different widths with a uniform and uneven of the valuable component content distribution over the volume and surface of the lump. The results obtained allow us to draw conclusions about the need for two-sided “inspection” for lumps that have an uneven valuable component content distribution over the volume and surface in order to eliminate the occurrence of the edge effect associated with the loss of information during the analysis and sorting of the lumps. For uniform valuable component content distribution over the volume and surface of the lump, the use of one-sided “inspection” is quite effective.
