Ilmenite Low Intensity Magnetic Separation

US3935094A - Magnetic separation of ilmenite - Google Patents

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.

A Novel Process for Titanium Sand by Magnetic Separation ...

May 07, 2015 · 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 ...

A discussion of magnetic separation techniques for ...

• Dry low intensity drum-type separators or ‘scalper’ ... Case Study 1: Dry magnetic separation of ilmenite before electrostatic separation The deposit for Case Study 1 was a typical aeolian reworked mineral sand deposit with a heavy mineral assemblage of ilmenite, rutile, zircon, sillimanite, monazite, ...

Magnetic Separation - an overview | ScienceDirect Topics

Commercial magnetic units follow a continuous separation process on a moving stream of dry or wet particles passing through a low or high magnetic field. The various magnetic separators are drum, cross-belt, roll, high-gradient magnetic separation, high-intensity magnetic separation, and low-intensity magnetic separation types.

Wet low intensity magnetic separators

Wet low intensity magnetic separators Iron ore processing General liming has produced several thousand Low In-tensity magnetic separators (LIMS) both dry and wet versions to the iron ore industry. liming has (in close co-operation with the iron ore mining Industry) developed and designed the low intensity magnetic separators to meet

Magnetic properties of ilmenite, hematite and oilsand ...

Upgrading of the LR Rutile was possible by using magnetic separation. With a low intensity magnetic separator (field intensity below 0.67 T), reduction roasting of the sample improved the separation. However, when a high intensity magnetic separator was used, the separation could be achieved without the need for reduction roasting.

Wet High Intensity Magnetic Separator - Mineral Technologies

Wet High Intensity Magnetic Separator WHIMS Production Separators Overview The Reading WHIMS set the industry benchmark for wet magnetic separation of fine minerals. They afford the most efficient separation of minerals in slurry form, when drying of the material is undesirable or …

LIMS dry drum - liming

limings LIMS dry drum low intensity magnetic separators consists of a stationary magnetic yoke with a number of permanent magnets placed inside a rotating drum of non-magnetic material.

ilmenite low intensity magnetic separator

2019 Manganese Ilmenite Gold Iron Magnetic separator. Grooved plates made of magnetic conductive stainless steel are used as a magnetic matrix. This separator features a short magnetic circuit, little magnetic flux leakage, high magnetic intensity, low energy consumption, a …

CONCENTRATION OF MAGNETITE/ILMENITE/& ASSOCIATED …

Low-Intensity Magnetic Separation* Gravity Concentration i - and sizing of Tailing Ilmenite has a specific gravity of 4.7 while that of garnet is in the order of 3.9. Although the difference is rather small, attempts were made to separate the two minerals by tabling after removal of the magnetite by low-intensity magnetic separa tion.

Magnetic separation - Wikipedia

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 ...

US5595347A - Process for separating ilmenite - Google Patents

A process for enhancing ilmenite from deposits of mineral sands or mineral concentrates comprises a single stage fluidized bed magnetizing roast (16). A temperature of 650° C.-900° C. in an excess of a carbonaceous fuel (such as coal/char, CO or hydrocarbon) is used to provide an atmosphere in which the oxygen potential is controlled resulting in a consistently high magnetic susceptibility ...

CHAPTER-8 BENEFICIATION OF IRON ORES

Der Waals, and capillary. 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. High intensity magnetic separators
