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

Ilmenite an overview ScienceDirect Topics

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

US4158041A Separation of ilmenite and rutile Google

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.

Selective sulphidation of impurities in weathered ilmenite

Jun 01, 2018· Existing processes based on a magnetising roast that are currently used to separate chrome-rich spinels from ilmenite do not always provide a clean separation as they are usually only applicable to deposits with a narrow range of compositional variation in both the ilmenite and the spinel (Pownceby and Fisher-White, 2006, Fisher-White et al., 2007, Bruckard et al., 2015).

Chromite Wikipedia

Chromite is a mineral that is an iron chromium oxide.It has a chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4).

Ilmenite Wikipedia

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.
