AbstractAbeneficiationteststudywasconductedonthelow-graderefractory tungstenpolymetallcores.Process mineralogy analysiswasusedtolarifyrecharacteritic，andtwoprocesssweresystematicallyompared：gravityseparationdominantprocess （coarseparticlegravityseparation-fineslmeflotation）andflotatiodominantproces（oughflotation-gavityseparationupgading）. Process parameters wereoptimized toreducecostsandachieveenvironmentalobjectives.The“ROMrough grinding-bulk Cu-S flotation-coarseparticlegravityseparation-fineslimeflotation”process wasultimatelyrecommended.Undertheconditionsof （204 0.17% WO grade and 0.18% Cu grade in the ROM ore，the following results were achieved： Tungsten concentrate： 33.97 % WO grade 3 3 at 66.38% recovery，Copper concentrate： 25.71% Cu grade at 83.87% recovery. Both processes showed comparable technical indicators，butthegravitydominantprocessdemonstratedsignificantlylowerreagentcostsandhigherretuwaterutilizationThis study provides technical foundations for enginering applications of similar low-grade tungsten polymetalic ores.
