  Reverse Column Flotation of Ultrafine Magnetite Mixture …

  202255 · Magnetite ores are among the most important sources of iron, which is in high demand in the global economy. Metallurgical properties of the magnetite concentrate significantly depend on impurities of silicon- and aluminum-bearing minerals. These impurities have to be separated from ore by magnetic separation and flotation techniques. …

  The effect of an external magnetic field on cationic flotation …

  201091 · In the current research the effect of the magnetic field during cationic flotation of quartz from magnetite has been investigated using a specially designed magnetic flotation column. The magnetic flotation column was designed to create a funnel-shaped magnetic field, and establish a downward magnetic force.

  Utilization of benzyl aminopropyl dimethoxymethylsilane as …

  2018121 · Abstract In this paper, a collector benzyl aminopropyl dimethoxymethylsilane (BADM) was utilized for the reverse flotation of silicate minerals from magnetite. The micro-flotation results showed that good floatability of quartz, garnet, olivine and magnetite was obtained at pH 8 in the presence of BADM.

  A Novel Sulfur-Containing Ionic Liquid Collector for the Reverse ...

  2022730 · The SCIL was used as a flotation collector for the first time to selectively separate pyrrhotite from magnetite by reverse flotation. Its flotation performance and adsorption mechanism on pyrrhotite or magnetite were investigated by microflotation tests, FTIR spectra, zeta potential and XPS analyses.

  Preparation and properties of dodecylamine microemulsion …

  In addition, it was found to have good adaptability to temperature and pulp pH, yielding a magnetite concentrate with 68.54% Fe and 3.60% SiO 2 from magnetite with 64.93% Fe and 9.12% SiO 2 using 45 g/t DDA microemulsion. Therefore, the proposed DDA microemulsion can be used as an efficient collector in the reverse flotation of magnetite.

  HIGH SALINITY WATER EFFECTS ON THE REVERSE …

  20151110 · The high silica content limits the usage of this iron ore concentrate. The feasibility of upgrading this iron ore concentrate by flotation has thus been investigated. It has been demonstrated that cationic reverse flotation process can reduce the silica grade in magnetite concentrate when performed with tap water from laboratories.
