Ilmenite is a naturally occurring mineral comprised primarily of titanium iron oxide, as well as other elements such as magnesium and manganese. It is highly magnetic and can be isolated from other minerals by magnetic separators and other metallurgical separation processes. The TiO 2 content of ilmenite ranges between 45-65 percent.
Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...
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.
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. Case Study 1: Dry magnetic separation of ilmenite before electrostatic separation The deposit for Case Study 1 was a typical aeolian
• A magnetic separator is generally classified as low intensity if its maximum field intensity is less than about 2000 gauss (H= 1.6 x 105 A/m, B=0.20 T). • 'Low intensity magnetic separators (LIMS) are used to treat ferromagnetic and highly paramagnetic minerals such as iron and magnetite.
Magnetic separators can be of the belt type or drum type. In the drum a permanent magnet is often located inside a rotating shell. Material passes under the drum on a belt. A belt separator is similar except that the magnet is located between pulleys around which a continuous belt travels. Magnetic separation has some limitations.
Application is illustrated in the separation of hematite and ilmenite from quartz. Bureau of Mines research on the magnetization of minerals started with an investigation of the magnetization time factor and later extended to a correlation of magnetic susceptibility with composition. This resulted in the design of a matrix-type separator.
Purified ilmenite and titanaugite were obtained from magnetic separation tailings of the vanadium–titanium magnetite ore located in Panzhihua, China. The tailings were first treated with weak magnetic separator and high-intensity magnetic separator, and then the concentrate was repeatedly purified using a Wilfrey shaking table.
Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
Circuit configurations can be quite variable and depend upon the heavily mineral assemblage of the feedstock. For example, a low ilmenite deposit would not require a magnetic separation circuit. ilmenite would typically be recovered from the rutile circuit magnetic separation stage.
The enhancement of ilmenite magnetic susceptibility by roasting is well known, and it is used routinely in the magnetic separation of mineral sands, yet surprisingly little appears to be known in ...
A typically low-grade titanium sand was first ground and then processed by low-intensity magnetic separation (LMS) and high gradient magnetic separation (HGMS) to recover titanomagnetite and ilmenite, respectively; as the TiO 2 grade of the sand is low, the primary treatment of the sand by magnetic separations is effective, with 78.45% by mass ...
Examples of these dry separators are the Readings IRM manufactured by Mineral Technologies They are commonly used to separate ilmenite from less magnetic and non magnetic in dry mills. The Readings IRM consists of an electromagnet which induces a magnetic field onto a serrated rotating roll via a cast iron pole located a short distance away.
ilmenite to allow magnetic separation from chromite. The intention of this paper is to give researchers new to the field an overview of the beneficiation of ilmenite through roasting and
A rotating magnetic field can be produced in a magnetic separator by using a magnet rotor fitted with alternate north-south magnetic poles, similar to the rotors currently used in modern eddy current separators. Rotation of the magnetic field causes ferromagnetic particles to rotate during magnetic separation. The particle rotation can then be used simply to...

Oct 11, 2018· Magnetic separation: Heavy minerals in the magnetic minerals are ilmenite, hematite, chromite, garnet, biotite, monazite and so on. Zircon is a non-magnetic mineral or a weakly magnetic mineral. Magnetic separation is divided into two types: dry type and wet type. Dry magnetic separation must be preheated before drying and grading.
This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.
