Adsorption Mechanism of Mixed Cationic/Anionic …
Maximum hematite floatation recovery was observed at acidic pH with sulfate, neutral pH with oleate, and at basic pH about 9.5 with C 12 amine. Accelerated adsorption of cationic collector in the presence of anionic collector apart from its own co-adsorption was observed in flotation results with quartz and hematite.
FLOTATION CHEMISTRY OF HEMATITE/OLEATE SYSTEM
these findings. Thus it has been shown that the hematite flotation using ole-ate as collector is highly sensitive to pH [10] and that the best flotation re-coveries are obtained in the pH range of 6-8 [1,3-8,10-12]. Also, increase in the conditioning temperature has been reported to significantly improve the hematite flotation response [5].
