The complexation of phosphates in thequartz-metal ion-H_2O-oleate system was studied.Computer assisted calculations with the aid of theadvanced program SOLGASWATER and knownequilibrium constants were used to evaluate themechanism,The calculation results revealed that inthe presence of a certain amount of phosphates,metal ions adsorbed at the quartz-H_2O interfacewill be transferred into solution.Thus the competi-tion for metal ions between phosphates and thequartz surface leads to surface deactivation and re-duced floatability.Various distribution diagramsclearly demonstrate the change of surfacecomplexation as a function of added phosphateconcentration.The deactivation products were alsoevaluated.
The complexation of phosphates in thequartz-metal ion-H20-oleate system was studied. Computer assisted calculations with the aid of the advanced program SOLASASWATER and knowquilibrium constants were used to evaluate themechanism, The calculation results revealed that inthe presence of a certain amount of phosphates, metal ions adsorbed at the quartz-H_2O interfacewill be transferred into solution. Thus the competi tion for metal ions between phosphates and the quartz surface leads to surface deactivation and re-duced floatability. Variety distribution diagrams clearly demonstrate the change of surface complexity as a function of added phosphateconcentration.The deactivation products were alsoevaluated.
