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.
Ilmenite mining process. Most ilmenite ore are poor ilmenite ore, so the ore processing must be carried out. Ilmenite ore beneficiation methods currently used for the mechanical selection (including washing, screening, re-election, high intensity magnetic separation and flotation), as well as fire enrichment, chemical processing method.
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 ...
The magnetic separator is used for mineral ore dressing of magnetite, pyrrhotite, ilmenite, wolframite, manganese, rare earth ore and other materials with a particle size of less than 3 mm, and is also used for iron removal operations of coal, non-metallic minerals, building materials and the like. Types of magnetic separator 1.
However, very little is known about the effects of roasting on the response of ilmenite and spinel particles to a rotating magnetic field. For example, although the optimal ilmenite roasting conditions for conventional magnetic separation are quite well established such conditions may or may not be optimal for RMF rotation separation.

These so-called placer deposits are often beach or fossil beach sands and contain other heavy minerals of commercial interest such as zircon and ilmenite. Monazite can be isolated as a nearly pure concentrate by the use of gravity, magnetic, and electrostatic separation. Monazite sand deposits are inevitably of the monazite- composition.

A discussion of magnetic separation techniques for concentrating ilmenite and chromite ores. The 6th International Heavy Minerals Conference ‘Back to Basics’, The Southern African Institute of Mining and Metallurgy, 2007. A discussion of magnetic separation techniques for concentrating ilmenite and chromite ores
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, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
The three samples of ilmenite ore from NE Poland used for the experiments were a non-magnetic product of the magnetic separation in the size range 0--0.25 mm with TiO2 contents of 10.4, 12.3, 3.9%, respectively. Before ilmenite flotation, sulphide minerals were floated out using potassium ethyl xanthate.
Jan 27, 1976· 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.
ABSTRACT OF THE DISCLOSURE 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.
In mineral processing, the flotation method can only realize the recovery of granular ilmenite less than 0.02mm to a certain extent, but there will be a lot of quartz and other veins in the fine ore powder after flotation, which seriously affects the flotation quality. Therefore, before flotation, the ore can be magnetic separation.
The grade of the TiO2 in the crude ore is 5.84%, the grade of the iron is 28.38%, and the form of the TiO2 mainly is ilmenite. Because of the TiO2 dense symbiosis with the iron, so the difficulty of the study is the effective separation of TiO2 and iron. After testing we decided take the process of grinding the crude ore, then get the iron concentrate through the high gradient magnetic separation.
An ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product. In this case all the gravity circuit including the jigs and tables can be eliminated. This scheme is also applicable on a rutile ore with little or no ilmenite.
