The removal of iron ion from leaching solution is critical for the recovery of value metals, with the method of choice commonly being crystallization precipitation. This paper summarized the new improvements in iron removal by precipitation methods in recent years and proposed a novel process, magnetic seeding and separation. The new process can promote iron precipitate
Magnetizing roasting followed by magnetic separation is a compound technique for the beneficiation optimization of Huangmei refractory limonite. The natural limonite samples are obtained from Huangmei, Hubei province. The samples are characterized by TG-DTG-DSC.
Processing results of limonite from leaching residue of gold ore It can be seen that, after removal of strongly magnetic magnetites with wet low-intensity drum magnetic separation, the limonite is effectively recovered with SLon pulsating high-gradient magnetic separator from the residue.

Magnetic separation of hematite and limonite fines as hydrophobic flocs from iron ores
1.Gravity separation of limonite-strong magnetic separation method . Generally, the method of limonite ore beneficiation can adopt the gravity separation-strong magnetic separation method to obtain a good separation effect, that is, the limonite ore is finely crushed or ground and then washed, sieved and classified and deslimed, and the coarse ...
While these low-grade iron ores, which generally contain amounts of hematite, siderite, and limonite, are difficult to be treated by magnetic separation, but they can be chemically transformed to ...
Results of investigation into the development of HIMS technology for separation of weakly magnetic finely disseminated limonite iron ores are discussed.
separation hematite and magnetite. Magnetic separation of hematite and limonite fines as ... The experimental results from this work have shown that an efficient magnetic separation of hematite and limonite weakly magnetic minerals in the fine size range can be achieved at a middle-intensity if the mineral fines are selectively and strongly aggregated, leading .
May 20, 2020 2 After grinding, the materials are sent into the magnetic separator by conveyor for wet magnetic separation, controlling the magnetic field strength at the range of 120-300 mT. 3 After magnetic separation, send the wet ore into the high-frequency vibrating screen and control the mesh size of 0.1 mm to 0.5 mm.
After magnetic separation, the Fe content in the quartz sand sample decreased from 2661ppm to 637ppm, which shows that magnetic separation has a significant effect on the removal of Fe impurities. And through experimental comparison, the quartz sand that has been subjected to acid leaching after magnetic separation has a better and faster iron ...
