magnetic separation. Case studies Several case studies are presented that describe the testing and flowsheet development work that enabled proper magnetic separation technology selection and flowsheet configuration.

Purification of ilmenite from chromite impurities by a two step magnetic separation wherein magnetically susceptible chromite is magnetically removed, followed by an oxidizing roasting of the ilmenite and a subsequent magnetic separation of ilmenite from the remaining chromite impurities to obtain an ilmenite with 1% or less chromite.
The ore is mainly composed of magnetite, hematite, martite, and quartz. It is very difficult to produce a high-quality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% -75 μm. Drum LIMS are then used to take out the magnetite particles, while drum MIMS (0.4
Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic.
Magnetic separation can be considered successful only if it produces the right quality of the concentrate with the right recovery. The desired magnetic induction and the field gradient are thus a function of the type of application, required metallurgical performance, and economic criteria.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
Magnetic separation. The method of magnetic separation is the process of separating ore from the gangue particles based on the magnetic properties of either ore or matrix. In this method, the ore is finely crushed and then passed over the magnetic roller, where one is magnetic
An interesting aspect of the magnetic separation of ore S (and partially ore I) is the enrichment of Mn in the magnetic concentrate. The amount of Mn was increased about 4 times from 0.4% and 0.2% in ores S and I, respectively, to 1.6% and 0.8% in the magnetic concentrates. The amount of Mn in the corresponding tails is more or less zero. SEM
A number of magnetic separation processes are used to study preparability of two main hematite-magnetite and magnetite-muscovite ore types extacted it the Abagas iron ore deposit. The dry magnetic
Between 2000 and 2010, magnetic separation and flotation were introduced to beneficiate the Sichuan rare earth ore. A combined “gravity-magnetic-flotation” process was developed (Li et al., 2002, Xiong and Chen, 2009), leading to significant increases in rare earth oxide (REO) content and recovery from the Maoniuping rare earth concentrate

Iron in magnesite concentrate powder would seriously endanger the quality of refractories. Slon-500 vertical ring pulsating and high gradient magnetic separator and CRIMM DCJB70-200 laboratory electromagnetic splint VPHGMS were used to remove iron from magnesite flotation concentrate powder produced in Haicheng region. The magnetic separation results showed that using CRIMM DCJB70
