Sensor-based sorting of tungsten ore

In conditions of decreasing quality of mined ores and, especially in cases when commercial components are contained in minerals with different physical properties, it is necessary to provide the processing technology with new approaches using the process of pre-concentration of the mined rock mass, implementing it through sorting of lump material based on sensorbased sorting. It is shown that the integration of XRL and XRF in the sorting of the rock mass that has undergone the stage of medium crushing, carried out on the material of substandard tungsten ores of the North Caucasus deposits, as well as using the XRT used in the process of sorting of skarn-scheelite-sulfide ore of the Vostok-2 deposit in Primorsky Krai, allows to isolate up to 40% of waste rocks with an outboard content of commercial components. At the same time, their content in the sorting concentrate increases by at least 1.55 times, and metal losses in the waste decrease from 5 to 8.5%. The results of flotation of the XRT concentrate demonstrate an increase in the through recovery of WO3 into the concentrate from 47% obtained during flotation of the initial lean ore to 89% during flotation of the preliminary enriched product in the sorting process
