    Jan 16, 2013 · The main advantage of the reverse micelle or emulsion technology is the diversity of nanoparticles that can be obtained by varying the nature and amount of surfactant and cosurfactant, the oil phase, or the reacting conditions. In addition, the size of the magnetite particle can be controlled by the temperature and the surfactant concentration .

    Micaceous minerals, known as layer silies, are counted mostly as the gangue minerals associated with valuable minerals, especially iron oxides. They mainly reject through the reverse flotation process using the ionic collectors,, ether amines, to improve process sustainability. Although ether amines have been applied for floating the wide range of silies, .

  • Extraction of Iron from Hematite

    Apr 21, 2020 · Hematite reverse flotation method is a method used for the extraction of iron from hematite, which uses ionic or ionic collectors to float gangue minerals from raw ore. The anionic collector reverse flotation method is mostly used when the pH value is 89. It is used to treat quartzcontaining gangue minerals.

    Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the lowgrade phosphate ore is, hence, of great necessity.
