magnetic separation of ilmenite

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.

Magnetic Separators For Mineral Process | Bunting - Redditch

Principles of Magnetic Separators. There are three magnetic properties of minerals. Each type enables separation using industrial magnetic equipment and are: Paramagnetic: Minerals that are only slightly affected by an applied magnetic field. They move towards concentration in lines of magnetic flux (e.g. hematite, ilmenite, and chromite).

ilmenite high intensity magnetic separation

High gradient magnetic separation (HGMS) has been an effective method for the concentration or removal of fine paramagnetic particles from suspension, but its powerful magnetic capture to magnetic particles results in the mechanical entrainment of nonmagnetic particles in magnetic product, and thus reduces the separation selectivity.

Centrifugal high gradient magnetic separation of fine ilmenite

Nov 10, 2017· High gradient magnetic separation (HGMS) has been an effective method for the concentration or removal of fine para-magnetic particles from suspension, but its powerful magnetic capture to magnetic particles results in the mechanical entrainment of non-magnetic particles in magnetic product, and thus reduces the separation selectivity.

Ilmenite Beneficiation by Roasting and Magnetic Separation ...

A new crude ilmenite beneficiation process was recently proposed that allowed for the preparation of a smelter grade ilmenite from ilmenite with elevated chromium content. Magnetising roasting was not utilised in the process. As part of this circuit an ilmenite low susceptible reject stream was produced that had a low magnetic susceptibility.

Magnetic separation of ilmenite - Quebec Iron and Titanium ...

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.

A discussion of magnetic separation techniques for ...

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

Recovery of titanium from beach sand by physical …

Ilmenite is recovered from the concentrate using wet magnetic separation, after drying, the non-magnetic concentrate is passed through electrostatic separators to separate rutile and zircon (Lanka Mineral Sand Ltd., 1999). In some plant operations, dry magnetic separation is employed, particularly for recovering of titanium bearing minerals ...

CHAPTER-8 BENEFICIATION OF IRON ORES

Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite (magnetic)
