摘要: Abstract The flocculation and selective behaviour of apatite-hematite system have been studied with sodium oleate as the flocculant silicate pyrophosphate dispersants. results show that is an effective apatite over a wide range pH, but dispersant in alkaline media neutral to acidic for hematite. Selective minerals has achieved from their mixture. Better selectivity obtained mixture higher hematite ratio. mechanisms involved discussed terms adsorption, dimerization precipitation oleate.
