The reviewed research works and patented developments serve as the basis for highlighting pre-requisites for revitalization of Tyrnyauzsky tungsten–molybdenum project based on geological mapping, reapparasail and optimized and efficient utilization of remaining reserves owing to X-ray fluorescent separation and selective concentration of various type ore (instead of gross concentration). The article describes the designed laboratory test benches and procedures for radio resonant separation and batched grading of ore, with distinguishing between different quality flows (the first test bench), and the dynamic studies of the efficiency of lump grading based on radiation exposure of a sample (lump) in the test zone, with the fixedly attached sides of the sample relative to radiation direction, and with useful signal recording (the second test bench). The structures, facilities and operation of the test benches are reported; the lab test results are presented, in particular, the value of 1 t of low-grade ore has been doubled owing to more efficient and optimized utilization.
