The present investigation was initiated to examine the significance and role of polysaccharides in the reverse flotation of iron ore. Since hematite is already hydrophilic at alkaline pH, where reverse flotation is taking place, the role of polysaccharides should be considered with respect to amine adsorption and maintaining …
The low-grade refractory hematite in Anshan, China is fine disseminated in a huge reserve and its flotation performance is often not satisfactory.
From the microflotation results, it has been found that the flotation response of galena fines is markedly improved due to the formation of hydrophobic flocs, …
Reverse froth flotation is the most commonly used concentration method for iron ores, where the quartz gangue is floated, while the iron oxides are depressed by starches. In this paper, the mechanisms related to iron ore anionic reverse flotation are investigated by flotation, electrokinetic and high pulp density (20% solids) adsorption …
In recent years, reverse anionic flotation has been successfully applied in China's major iron ore area, Anshan (Shen and Huang, 2005, Zhang et al., 2006). ... Hesleiner et al., 1991), the surface charge of hematite in reverse cationic flotation (pH 10–10.5) would be relatively low. Before adding starch to flotation pulp, the repulsive ...
In order to enhance the reverse flotation effect of hematite, dodecyl trimethyl ammonium chloride (DTAC) and a mixed anionic/cationic collector of DTAC and tall oil were selected for flotation studies on quartz and hematite. Surface tension tests, FT-IR, XPS analysis, and molecular dynamics (MD) simulations were also conducted in …
Nanobubbles were able to enhance reverse anionic flotation of hematite. Different flotation reagents were investigated for their impacts on reverse nanobubble …
Hematite is commonly upgraded in China using a reverse anionic flotation process with starch as depressant for hematite, Ca 2+ as activator and fatty acids as collector for quartz. The Anshan type of hematite is well known for its low grade, fine …
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 …
The invention provides an anion collecting agent for reverse flotation of Anshan type lean hematite ore at a normal temperature. The anion collecting agent is composed of C16H31COCH(COONa)2 and one or more of ricinoleic acid, vegetable oleic acid, animal oleic acid or cottonseed oleic acid, wherein C16H31- refers to linear chain alkenyl with …

The reverse cationic flotation route widely used in the iron ore industry is less selective for alumina/hematite separation than for quartz/hematite separation. Das et al.[28] studied the beneficiation of some alumina-rich iron ores and reported that to reduce alumina content by 4%, as much as 45% Fe has to be lost in the beneficiation process.
