Mycobacterium phlei as a flotation collector for hematite ...
1993-11-1 Mycobacterium phlei has very good potential as a hematite flotation collector. The flotation recovery of hematite is dependent upon the solution pH and concentration of the microorganism. The critical pH for maximum recovery of hematite is around three, which corresponds to the point of zero charge of the microorganism. An excellent correlation between the flotation recovery and bacterial

Adsorption mechanism of mixed collector systems on ...
2012-1-1 Hallimond flotation response of hematite as a function of pH and collector concentration was investigated. The study revealed that hematite flotation recovery is maximum at acidic pH with sulphate, at neutral pH 6–7 with oleate, and at basic pH about 9.5 with C 12 amine. It is the first time that the hematite flotation results show an increased adsorption of cationic collector in the presence of anionic
