Mineral and Technological Features of Magnetite–Hematite

12 hours ago The extremely small size of hematite segregations and thin intergrowths with quartz can lead to incomplete liberation of hematite during its grinding and, as a consequence, to the concentration of the mineral in the tailings, and microinclusions of gangue minerals in hematite can significantly reduce the quality of the hematite concentrate.

Flotation recovery of rare earth oxides from hematite

A previous investigation has identified almost identical flotation response between monazite and hematite in the presence of anionic collectors. Therefore, it is necessary to investigate the feasibility of selective flotation of rare earth oxides (REO) in monazite from hematite–quartz mixtures, to identify cost-effective processing methods.

Influence of aggregation/dispersion state of hydrophilic

Experimental data collected from batch flotation were fitted to Warren’s models, indicating that the fine hematite was primarily recovered into froth through entrainment rather than true flotation in the presence of high dosage of corn starch or corn dextrin as a depressant (>500 g/t).

US4342648A Direct flotation of pyrochlore Google Patents

Direct flotation of pyrochlore from its ore can be carried out at acidic pH using 1-amidoethyl-2-substituted imidazolines of the formula ##STR1## wherein R and R' are independently alkyl or alkenyl of 8 to 22 carbons, or their salts. In the presence of large amounts of carbonate in the ore, the pulp is acidified with hydrofluoric acid, fluosilicic acid, or their acid reacting compounds.

Interactive effect of minerals in the flotation of complex

(1) Fine valuable minerals adhere to the coarse gangue minerals, which leads to the passive loss of valuable minerals. In hematite (Fe 2 O 3) flotation, for example, fine hematite particles can be adsorbed on the surface of quartz, resulting in a reduction of hematite recovery [19];

Role of Surfactants in Mineral Processing: An Overview

Nov 10, 2018 Froth flotation process, which uses the difference in hydrophobicity of minerals, is employed in several industries (mineral processing and others) for fines processing. It is a process of upgradation of minerals by taking advantage of differences in physico-chemical surface properties between valuable and gangue minerals of two different minerals.

Effect and mechanism of dolomite with different size

Mar 30, 2016 The effect of dolomite with different particle size fractions on hematite flotation was studied using sodium oleate as collector at pH of about 9. The effect mechanism of dolomite on hematite flotation was investigated by means of solution chemistry, ultraviolet spectrophotometry (UV), inductively coupled plasma atomic emission spectrometry (ICP-AES) and X-ray photoelectron spectroscopy (XPS).
