Iron ore beneficiation technology, reverse flotation ...

As long as the monomer is separated by grinding, the amine collector can float the monomer quartz well. (2)Ore containing hematite and magnetite, because magnetite is not easy to float, the combined process of magnetic separation→flotation is commonly used for separation. However, if the gangue is collected by a cationic collector, both hematite and magnetite will remain in the tank to be recovered,

Reverse Combined Microflotation of Fine Magnetite

Magnetite is an essential iron-bearing mineral. The primary method of magnetite ore beneficiation involves successive steps of crushing, grinding, and magnetic separation. Reverse cationic flotation is used at the final stage to remove silicate and aluminosilicate impurities from the magnetite concentrate and reduce silica content to 1–3%, depending on metallurgical processing route ...

Improving reverse flotation of magnetite ore using

01/07/2019  Reverse cationic flotation is an effective process used in the beneficiation of oxidized iron ores (Filippov et al., 2010, Eisele and Kawatra, 2007, Nakhaei and Irannajad, 2018). In this process, quartz, which serves as the main gangue mineral, is floated with cationic collectors (amines) (Filippov et al., 2014, Araujo et al., 2005). However, even low amine adsorption promotes the flotation of
