FLOTATION OF QUARTZ AND HEMATITE: ADSORPTION

It was observed that hematite flotation recovery is maximum at acidic pH with sodium dodecyl sulphate (SDS), neutral pH with oleate, and at basic pH about 9.5 with C. 12. amine. Flotation results with both quartz and hematite indicate an increased adsorption of cationic collector in the presence of anionic collector apart from its own co-adsorption. The incorporation of oleate in between C. 12,Mycobacterium phlei as a flotation collector for hematite,,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,A study of flotation characteristics of monazite, hematite,,10.01.2017· Hematite flotation recoveries were higher than that of monazite at pH 3, 5, and 11. However, it can also be observed that the collecting ability of AH on quartz mineral was poor, with quartz recovery decreasing with increase in pH. 3.4.2. Effect of collector dosage.

01.01.2012· The flotation response of hematite as a function of pH at fixed cationic and anionic collector concentration is shown in Fig. 1.Results clearly indicate that with cationic C 12 amine collector the flotation recovery increases with the increase of pH till around pH 9.5 and thereafter, the recovery decreases marginally. A maximum recovery, with C 12 amine, of about 60% is attained at pH 9.5.Effect of particle size on flotation performance of hematite,flotation, hematite can be floated with fatty acid as collector, while silicate minerals are depressed. For the reverse flotation, hematite is depressed with the help of starch, and the silicate minerals (such as quartz) are floated by using calcium ion as activator of quartz and fatty acid as collector under strong alkaline conditions (Kar et al., 2013; Shrimali et al., 2018; Shrimali et al,Oil-assisted flotation of fine hematite using sodium,,Oil-assisted flotation of fine hematite using sodium oleate or hydroxamic acids as a collector Hao Li 1, Mingxia Liu 2, Qi Liu 1 1 Department of Chemical and Materials Engineering, University of Alberta, Edmonton, Alberta, Canada T6G 1H9 2 School of Minerals Processing and Bioengineering, Central South University, Changsha, Hunan, P.R.
