cationic flotation of fine quartz

Production of Magnetic Superconcentrates by Cationic FlotationTo study the production of superconcentrate by cationic flotation of quartz, a sample of magnetic concentrate was obtained from a commercial producer on the Mesabi range. Eighty percent of the material was minus 325 mesh, yet only 40 per-cent of the silica was contained in this size fraction.Flotation of fine particles in the presence of combined ...In addition, quartz is often floated in the reverse cationic flotation of iron ores which makes it industrially attractive (Filippov et al., 2014). The effects of air flow rate, collector dosage and particle size are also studied. These factors affect the flotation performance of fine particles but have not yet been addressed by other ...Interfacial Behavior of Anionic/Cationic Flotation ...In this study, the effects of anionic/cationic collector mixtures on surface tension (γ ) were investigated as a function of pH using the pendant drop method.For the tests, long‐chain tallow amine and petroleum sulfonate, which are the most common anionic and cationic flotation collectors, were used individually and as binary mixtures with different mixing ratios.
