The effects of pH and dispersant concentration on the selective flocculation of celestite mineral were studied. Experiments carried out with sodium silicate at optimum conditions yielded a concentrate, which is flocculated material, assaying 82.5% SrSO(4) with a recovery 79% and separation index of 0.62 front a mixture containing 50% SrSO(4).eninfo:eu-repo/semantics/closedAccessCelestiteCalciteSelective flocculationAero 845DispersantConference Object211216N/AWOS:000275795400027N/A
