Effect of three collectors on the flotation rate of kyanite
The flotation performance of sodium petroleum sulfonates with different molecular weights was evaluated for flotation of a kyanite ore, by investigating valuable mineral recovery Ferric ions produced during grinding influence the flotation separation between kyanite and quartz adversely. In this study, citric acid was used as a regulator to eliminate the effect of ferric ions on the separation of kyanite from quartz with sodium oleate (NaOL) as a collector. The microflotation test results indicated that the quartz was Elimination of Ferric Ion Effect on Separation between Kyanite

Kyanite and sillimanite are two polymorphic minerals with the same formula of Al2SiO5, but different crystal structures. Despite their high economic values, selectively recovering them by flotation is a challenge. In this study, the flotation behaviors of the two minerals with sodium oleate as the collector were examined at different pH Flotation behavior of calcite and aragonite with a sodium oleate collector was studied. The mechanism for the difference in flotation recovery and kinetics of the two minerals was analyzed via adsorption quantity, microcalorimetry, flotation diffraction method, and calculation of unsaturated bond density on mineral exposed planes.Results Flotation behavior and mechanism of calcium carbonate

Flotation behavior and mechanism of calcium carbonate
1. Introduction. Polymorphs refer to crystals with the same chemical composition but different structures formed under varying physical and chemical conditions; they are commonly found in natural minerals, such as hexagonal and monoclinic of pyrrhotite, pyrite and marcasite, andalusite and kyanite [[1], [2], [3], [4]].The surface Kyanite to be used in the refractory industry should be free from impurities such as Fe 2 O 3,TiO 2,CaO, MgO, Na 2 O and K 2 O as much as possible since they affect refractoriness. As there is no standard specification for kyanite, different countries have their own limits for the minimum grade that it varies considerably from country to 10.1016/j.minpro.2003.08.001 DeepDyve
