Jun 01, 2020· Magnetic separation of OCAC material is an effective method to partially separate reactive material from low quality oxygen carrier material. Buildup of ash layers and increased porosity strengthen the material mechanically and make it less sensitive to the stresses inflicted upon the material in the reactor both as a result of the fluidization and the oxidizing and reducing environment.Cited by: 4

Feb 15, 2019· To effectively separate ilmenite from titanaugite by magnetic separation, the magnetic coating method was introduced to increase their magnetic difference. Sodium silicate depressant and sodium oleate collector were introduced to strengthen the selective coating behaviour of magnetite [Cited by: 17
The matrix rotation improves capture probability and recovery for magnetic particles. Centrifugal HGMS achieves an improved separation performance for fine ilmenite. Centrifugal HGMS presents a new method for separation of para-magnetic minerals.Cited by: 16
Nov 10, 2017· Abstract. 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. HGMS in centrifugal field (CHGMS) is proposedCited by: 16
Apr 01, 2020· According to the results and discussions in this study, the magnetic separation of ilmenite from titanaugite was achieved by the assistance of magnetic coating. After treated by magnetic coating, the recovery of ilmenite was increased by approximately 36% and the TiO 2 grade enhanced 2% in the magnetic separation of mixed minerals. These results were attributed to the enlarging magnetism difference between ilmeniteCited by: 5

DUNN* *Outotec (USA) Inc.—Minerals Processing, Physical Separation Magnetic separation has long been used to upgrade and beneficiate a wide variety of industrial minerals.646KB
Mineralogy, physical characterization and magnetic separation performance were investigated for purification of a raw ilmenite concentrate. With the aid of mineral liberation analyzer (MLA) and ...
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...
been concentrated by high-gradient magnetic separation and flotation. The ilmenite concentrate can be treated with sulphuric acid to obtain titanium dioxide (titanium white) or by high-temperature smelting to produce high-titanium slag. Approximately 30% of the titanium from raw vanadium titanomagnetite can be recovered into an ilmenite concentrate. Low-intensity magnetic separation can

the ilmenite concentrate processing by microwaves and the microwave cavity design. The conventional methods used in the processing of ilmenite ores are gravity separation, high intensity magnetic separation (HIMS), Electrostatic separation or a conjunction of them. In order
Magnetic separation equipment can separate many minerals, such as magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate, metallurgical manganese ore, manganese oxide, iron ore, kaolin, rare earth ore, etc. Magnetic separation process is in the magnetic field of magnetic separator, with the help of magnetic and mechanical force on the role ...
separator reportedly was also used for the purification of quartz and kaolin (Chen et al., 2012). Nowadays, pulsating HGMS (PHGMS) separators are widely used for separation of magnetic metallic ores such as hematite, limonite and ilmenite (Chen and Xiong, 2015). In the recent decade, PHGMS has been gaining numerous applications
Further, the samples were subjected to magnetic separation using Permroll (14,000 Gauss) to separate magnetic and non-magnetic fractions and the representative weight percentages were recorded. The magnetic fraction was subjected to Carpco high tension separator (laboratory model, drum type) to recover conducting minerals (ilmenite and rutile).
