Ilmenite Rutile Separate - Soby

Ilmenite can be converted into pigment grade titanium dioxide via either the sulfate process or the chloride process. Ilmenite can also be improved and purified to Rutile using the Becher process. Ilmenite ores can also be converted to liquid iron and a titanium rich slag using a smelting process. Prices / Quote.

How to Separate Ilmenite? - Mining-pedia

The grade of ilmenite selected by this method can be directly raised to more than 30% after reprocessing and the final titanium concentrate grade can reach 47% after flotation desulfurization and other processes and the recovery rate is close to 30% and the sulfur concentrate with a grade of 40% can be produced at the same time.

Ilmenite beneficiation flotation mineral flotation systems ...

Used for agglomeration flotation of ilmenite it means to make the ilmenite hydrophobic by the collector adsorbed on the surface of the ilmenite and then use the capillary attraction of the bridge liquid to agglomerate the ore particles and then separate them after floating.It should be noted that in the process of beneficiation with agglomeration flotation the strength and strength of the stirring must be ensured at all times so that the ore particles can be more easily aggregated into ...

2020/06/15& 0183;& 32;The ilmenite ore utilised in the actual mineral flotation was supplied by a mining company in Yanbian County Sichuan Province. The ore sample was a gravity concentrate and the chemical analysis results are summarised in Table 2. The ilmenite ore contained 21.52% TiO 2 20.75% TFe 10.30% CaO and 7.01% MgO. Get Price

Flotation behaviors of ilmenite titanaugite and forsterite ...

The results of the artificially mixed minerals flotation experiment demonstrate that the concentrate of TiO 2 grade increases from 16.92% to 30.19% at pH 5.4 and a weakly acidic solution is the appropriate condition for the flotation separation of ilmenite from titanaugite and forsterite.

Activation Mechanism of Lead(II) to Ilmenite Flotation Using ...

of the titanium industry comprise ilmenite (FeTiO3) and rutile (TiO2). In China ilmenite ore has ranked first for the production of Ti metal primarily due to the excessive exploitation and progressive exhaustion of rutile ore in the past [34]. Gravity magnetic and electrostatic separations which have

Ilmenite Recovery by Combined Processing Method

In mineral processing the flotation method can only realize the recovery of granular ilmenite less than 0.02mm to a certain extent but there will be a lot of quartz and other veins in the fine ore powder after flotation which seriously affects the flotation quality. Therefore before flotation the ore can be magnetic separation.

Ilmenite ores can also be converted to liquid iron and a titanium-rich slag using a smelting process.

US5106489A - Zircon-rutile-ilmenite froth flotation process ...

This invention relates to a method for recovering a bulk concentrate of zircon and a bulk concentrate of rutile-ilmenite from dry plant tailings. A process has been discovered for froth flotation by manipulating the surface charges of dry plant tailings.

Ilmenite - CONCENTRATION OF MINERALS

Ilmenite is the titanium-iron oxide mineral with the idealized formula FeTiO 3. It is a weakly magnetic black or steel-gray solid. Altered ilmenite forms the mineral leucoxene an important source of titanium in heavy mineral sands ore deposits. Leucoxene is a typical component of altered gabbro and diorite and is generally indicative of ...

US2557455A - Flotation of ilmenite ores - Google Patents

The conditioned pulp was diluted to 20% solids and a rougher ilmenite concentrate taken for 4 minutes. This concentrate was given a cleaner and recleaner flotation of 3 minutes each without...

Titanium Ore Processing and Beneficiation

Flotation of Titanium Fines. Filtering and Drying. Magnetic and Electrostatic Separation. Possibilities For All Flotation Treatment of Titanium Ore. To develop a flowsheet for separation of high grade titanium-rutile from ilmenite that will meet market requirements. Rutile has a SG of 4.2 hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0 hardness of 5.0 to 6.0 and is weakly magnetic.

Surface Modification and Column Flotation of a Massive ...

A column cell was used to minimize the negative effect of slimes on ilmenite separation efficiency. When ilmenite flotation was performed in a 1 litre Denver cell the flotation recovery of titanium dioxide from the ilmenite ore sample was only 68.5% (31.1% TiO 2) under conventional flotation conditions. After microwave radiation pre-treatment for three minutes at 2600 W and 2.45 GHz the ferrous ions on ilmenite particle surfaces were converted into ferric ions; hence the recovery ...

Beneficiation of massive ilmenite by froth flotation ...

The ore could be enriched to a maximum TiO 2 content of only 37% at a pH of 10.75 pulp density of about 150–175 g/litre and at a collector concentration of 1.25 kg/tonne of ore. In the second approach the ilmenite was made to float in an acidic medium with a combination of anionic and cationic collectors (oleic acid and lauryl trimethyl ammonium bromide respectively) and with soda ash and sodium hexametaphosphate usages of 0.1 and 0.2 kg/tonne of ore respectively as the depressants for ...
