    US4158041A - Separation of ilmenite and rutile - Google Patents. 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

    separation to produce an ilmenite concentrate for hydrometallurgical testing. The beneficiation process resulted in three final products: high silica tailings, magnetite/titanomagnetite concentrate, and ilmenite concentrate. The ilmenite concentrate was found to have the following chemical assay: 38.9% TiO 2, 31.1% Total Fe, 6.4% SiO 2

    May 09, 2016 Magnetic and Electrostatic Separation. Concentrates containing rutile, ilmenite, magnetite, zircon and possibly silica are sized over a vibrating screen and collected in separate storage hoppers ahead of dry processing, as each size is treated separately. Low intensity magnetic separation pulls out metallic iron and magnetite

    Ilmenite is heavier than silica. The expectation is that the ilmenite particles will settle at the bottom of ridges in-between ri es. The silica particles, as they are closer to the top of the ridges, should be carried by the owing water towards the tailings launder. On the other hand, the ilmenite particles will travel across the table (in-between the ri es), forming a curved pro

    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

    It can be seen that high-gradient magnetic separation plays a crucially important role in the recovery of fine ilmenite from the ore. In the flowsheet as shown in Figure 21, the feed is firstly processed by wet low-intensity drum magnetic separation to concentrate vanadic titano-magnetite, and then is effectively processed through an SLon pulsating high-gradient magnetic separation flowsheet
