Hematite PTMS magnetic separation iron removal method: mainly after the removal of other impurity ions, at the temperature of 200℃, pressure of 1.7-2.0MPa autoclave oxygen, iron oxidation, hematite (Fe ₂ O ₃) form precipitation removal, this method of iron slag less, high metal recovery, can comprehensive recovery of a variety of valuable metal, but need expensive high pressure equipment, operating conditions are difficult to control.
PTMS magnetic separation Redox method: by regulating the redox state of iron ions to change its properties in the system to achieve the purpose of iron removal. For example, after the oxidation of ferric iron to trivalent iron, ferric iron ions are more likely to hydrolyze to form precipitation under certain pH conditions. In some non-ferrous metal solutions, oxidants (such as oxygen, air, hydrogen peroxide, etc.) may be used to convert iron ions into iron ions.
Chemical reactions are used to convert iron ions in solution into insoluble precipitate, thus achieving separation from other metal ions. In the field of PTMS magnetic separation hydrometallurgy, there are common iron removal, needle iron removal, hematite, etc. In some low-grade magnetite deposits, magnetic separation increases the ore grade to levels that can be used for smelting.
