The relation of parameters of uranium ores dressing by the X-ray radiometric method from their distribution into sizes is established. The parameters, describing on washability of poor uranium ores, depending on fineness of aggregate of chunks of sorted ore (from —200 mm up to +25 mm) vary as follows: the output of lean ore in a concentrate oscillates varies from 11.25 %; the output of tailings of sorting for lean ores varies from 89.74 %; extraction of uranium compounds of lean ores in a concentrate amounts 61 up to 92 %. Most effectively lean ores are exposed to sorting at an abatement of fineness of aggregate of chunks from —200 up to +25 mm. Taking into account that during the trammeling the top size product is removed with the off-grade contents of uranium and enriched fine ore, in process of lumpy separation of a machine class, all ore mining mass can be separated into: raw material for dry backfill compounds, makes up 55 %, raw material for in-situ leaching (ISL) — 14 %, raw material for processing by hydrometallurgical technology (HMT) — 31 % |
