Obtaining the x-ray fluorescence separator experimental separation characteristics for oxidized copper ore

Use of pre-concentration methods increases in general, and use of X-ray fluorescence separation increases in particular. So frequently requires the description of this process from a theoretical standpoint. The main aim of any separation process is to forecast the technological parameters of separation. The forecast of separation indicators is carried out using the fractional characteristics of raw materials and the separation characteristics of the equipment used for the separation process. The paper describes a technique for obtaining separation characteristics of the X-ray fluorescence separation process using a laboratory X-ray fluorescence separator SRF-100L. Experiments were carried out in the sorting mode on a sample of lumpy material for two variants of the assigned separation boundaries, a statistical analysis of the data obtained was carried out. The surface content of the component in the lumps of material was estimated by means of an average spectral ratio. It is revealed that the values of the average spectral ratios for each lump are different in different experiments to obtain a separation characteristic, but this difference is insignificant. It is revealed that as a measure of the heterogeneity of surface mineralization, the mean square deviation of the spectral ratio can be used for several implementations of separation of the same lump. The described methodology makes it possible to obtain experimental separation characteristics for different types of mineral raw materials. Taking into account the separation characteristics of industrial equipment of this type when calculating separation indicators allows make a forecast with greater accuracy.
