sulfate process in ilmenite

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.

Sulfation Leaching Treatment ilmenite Concentrate

Sulfate process plants, which produce less than 30 pct of the TiO2, are based on the dissolution of ilmenite and/or titanium slag in sulfuric acid. Iron sulfate is separated by crystallization, and the remaining solution is diluted to precipitated hydrated TiO2, which is calcined to TiO2. Chloride process technology, which is environmentally cleaner and generates less waste materials than the ...

Titanium Dioxide (TiO2) Production and Manufacturing

TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores. However, it

PT. Monokem Surya

Sulfate process plants must utilise low-vanadium ilmenite, as vanadium is a penalty element. Titanium dioxide pigment can also be produced from higher titanium feedstocks such as rutile and leucoxene via a chloride acid process. Ilmenite sand is also used as a sandblasting agent

Meide Group USA Inc. SULFATE PROCESS

Sulfate process is one of the processes for producing Titanium Dioxide (Anatase and Rutile). For sulfate process, ilmenite (FeTiO3) has been used as a feedstock material. The inlet stream is reacted with concentrated sulfuric acid (H2SO4) to extract the converted Titanium Oxygen Sulfate (TiOSO4).

Titanium dioxide - Essential stone Industry

There are two main processes, the Sulfate Process and the Chloride Process (Table 1) which use the two principal ores, ilmenite and rutile, respectively. Ilmenite contains 45-60% TiO 2 and rutile contains up to 99% TiO 2 .

sulfate process in ilmenite – Grinding Mill China

Ilmenite – Wikipedia, the free encyclopedia. Sulfate process plants must utilise low-vanadium ilmenite, as vanadium is a penalty element. Titanium dioxide pigment can also be produced from higher titanium

Chloride process - Wikipedia

The chloride process is used to separate titanium from its ores. In this process, the feedstock is treated at 1000 °C with carbon and chlorine gas, giving titanium tetrachloride . Typical is the conversion starting from the ore ilmenite : [1]

US4085190A - Production of rutile from ilmenite - Google ...

According to this process, low grade ilmenite ore 30 having TiO 2 equivalent contents of less than 50 wt % TiO 2 and iron contents of in excess of 30 wt percent iron as iron oxides is admixed with a molecular equivalent of calcium sulphate 3 and is introduced into reduction furnace 4.

WO2002087770A1 - Upgrading ilmenite for titania

The present invention provides a process for upgrading a primary ilmenite containing gangue mineral grains for forming titania pigment by the sulfate method, the process including the step of: roasting a primary ilmenite containing gangue mineral grains at a temperature of less than 650 °C under conditions that promote the formation of a ...

TITANIUM TETRACHLORIDE PRODUCTION BY THE CHLORIDE -

As in the chloride process, the chloride-ilmenite process takes place in a fluid bed reactor in which the ore is chlorinated, in the presence of coke as a reducing agent.

processing of ilmenite ore - polarstudie.nl

Ilmenite is the most abundant titanium dioxide-bearing ore containing (up to three times less) than the sulfate process (DuPont 2014) Naturally occurring rutile ore is the preferred raw material for the chloride process that the use of a mixed chloride lixiviant of hydrochloric acid and magnesium chloride offers advantages in View quotes...
