Flotation chemistry of hematite/oleate system

1980-7-1  5. Like other oleate flotation systems, hematite%leate system also needs prolonged conditioning time especially under pH levels below 8-0 where o'eate adsorption at liquid air interface as well as ahematite surface is rather slow. 6. Conditior mig is a critical step in the flotation operation of this system.

2019-6-1  The depression of hematite in the reverse flotation system of oleate-starch-hematite was investigated at the atomic level by atomic force microscopy (AFM) combined with density functional theory (DFT). AFM imaging and cross-sectional imaging show that the adsorption configurations of oleate and starch on hematite were in shuttle and flake patterns, respectively, resulting in a greater

Flocculation and flotation characteristics of fine

2003-9-29  Sodium oleate, a very common and typical collector for oxide minerals, has been used for many years. It has been also indicated that oleate is a superior collector for hematite flotation. This historical background makes it attractive to investigate the flocculation characteristics and mechanism of the hematite–oleate system.

2017-6-30  The effects of carbonate minerals (dolomite and siderite) on the flotation of hematite using sodium oleate as a collector were investigated through flotation tests, supplemented by dissolution measurements, solution chemistry calculations, zeta-potential measurements, Fourier transform infrared (FTIR) spectroscopic studies, and X-ray photoelectron spectroscopy (XPS) analyses.

Effect of sodium alginate on reverse flotation of

2018-10-2  Given the gradual increase in the chlorite content of hematite ores, pulp properties seriously deteriorate during flotation. The traditional anion reverse flotation of hematite cannot effectively eliminate the effects of chlorite, leading to a significant decrease in the total Fe (TFe) grade of the concentrate. In this work, the effect of sodium alginate on the reverse flotation of hematite

2019-6-30  Fig. 1(a) and (b) are height images of clean hematite in 2D and 3D, respectively. From these it can be inferred that the hematite crystal particles were hexagonal, indicating that hematite belongs to a hexagonal crystal system, and Fig. 1(b) confirms that the surfaces of the hematite particles were smooth without any projections. Oleate on the hematite surface is captured in Fig. 1(c) and (d).

Effect of 25% Goethite on the Hydrophobicity and

2012-1-2  Flotation tests conducted on the two Iron Duke samples using oleate showed that the presence of goethite adversely affected the flotation response of the hematite but contact angle measurements showed a higher hydrophobicity for the sample containing 25% goethite. Correcting the oleate addition for the changes in surface area still showed that the goethite reduced the flotability of the hematite.
