Flotation Chemistry of Hematite/oleate System
Oleate flotation characteristics of hematite have been investigated in thjs study under a wide range of experimental conditions of pH, temperature, ionic strength and collector concentration. The study revealed the following major features of this system which include: (a) a maximum in floatability in the neutral pH range; (b) an increase in the flotation response of hematite with increase eith...
متن کاملTOF-SIMS studies of surface chemistry of minerals subjected to flotation separation – A review
This paper reviews the applications of time of flight secondary ion mass spectrometry (TOF-SIMS) used for surface chemical analysis of mineral in the context of froth flotation. A wide range of applications are reviewed, including; interactions of reagents on the surface of mineral phases during flotation separation, determining the effects of various transferred ions from different minerals or...
متن کاملAn Investigation on the Surface Chemistry of Some Rare Earth Minerals during Flotation by Tof-sims
The Thor lake deposit is a world class resource of rare earth (REE) metals and minerals in Canada. Development work to optimize a REE mineral recovery process flow sheet is underway, however, given the ore mineralogy; the developed reagent scheme is relatively complex. As part of a research project, micro flotation tests were conducted on a feed sample in order to examine factors affecting stre...
