Annotation It is noted that the content of valuable components in the products of separation is one of the main technological indicators by which the effectiveness of any separation method is evaluated. One of the methods of separation is the induction radio-resonance method. For some types of ore in mineral resources, the presence of minerals with a high magnetic susceptibility in the ore, for example, for sulphide copper-nickel ores such a mineral is magnetite. In order to increase the sensitivity and expand the boundary of the separation feature of sulfide-containing minerals from rock studies, they were conducted at higher frequencies. The operating frequency during the studies was varied by a master oscillator in the range 1,1...15 MHz. Estimation of the efficiency of the radio-resonance separation method in solving the problem of separation of ores into concentrates and tails was carried out at the maximum yield of tailings. The methodology for assessing performance indicators is based on simulating the separation by repeatedly sorting pieces of the original sample for different values of the separation boundaries. Experimental studies of enrichment by induction method were carried out on lump products of oxidized and non-oxidized sulphide ore. The authors made the following conclusions: when introducing a piece into the radio-resonance circuit, the sulphide minerals significantly change the quality factor of the circuit, and not the frequency. The given researches are put in the development of the electron-solving block. In the course of the experiments, the values of the parameters of the separation feature were determined. This allowed, when setting the separation boundaries at different levels, to get the output of the tailings to the sorted class -40...+ 20 mm. Analysis of the obtained data by the radio resonance method indicates that the values of the tailfall tailings are increased by 16 %, and the content of the useful component in the concentrate increases by 2,4 %, hence the values of the technological efficiency indicators indicate the promise of the radioresonant enrichment method
