Kinetics of the dissolution of ilmenite in sulfuric acid

01/06/2010· One of the main commercial processes for the production of titanium dioxide pigment from ilmenite minerals is the Sulfate Process (Barksdale, 1966, Mackey, 1994, Lasheen, 2009). It accounts for about 40% of world production for pigment titanium dioxide (Adams et al., 1997, Wang et al., 2009, Liang et al., 2005).

Ilmenite/Rutile Alpha Thermal Process

TiO 2 pigment is produced from titanium mineral concentrates by either the chloride process or the sulfate process. In the sulfate process, ilmenite or titanium slag is reacted with sulfuric acid. Titanium hydroxide is then precipitated by hydrolysis, filtered, and calcined. In the chloride process, rutile is converted to TiCl 4 by chlorination in the presence of petroleum coke. TiCl 4 is

Ilmenite Wikipedia

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.

SULFATE PROCESS Meide Group USA Inc.

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). Such reaction can be observed as equation 1 listed below: FeTiO3+ 2H2SO4 --> FeSO4 + TiOSO4 +

Ilmenite Processing By Slag Procedure

Sulfate process (Kirk-Othmer, 1997; Kirk-Othmer, 2006; DeMerlis, 2005) Both anatase and rutile grades of titanium dioxide can be produced by the sulfate process, depending on particular processing conditions. Briefly, ilmenite or ilmenite and titanium slag is digested with sulfuric acid and the product is diluted with water or dilute acid. Layanan Online . Case 3: Ilmenite (FeTiO3) Smelting

Ferrous Sulfate Manufacturing Techniques & The Affinity

Specifically, the process used to create titanium dioxide is called the sulfate process. This involves dissolving ilmenite which is a black iron-titanium oxide, then forming hydrated titanium dioxide, and finally forming anhydrous titanium dioxide. This is the chemical reaction: FeTiO 3 (s) + 2H 2 SO 4 (aq) -> TiOSO 4 (aq) + FeSO 4 (aq) + 2H 2 O (l) In plain English, combining ilmenite with

Titanium Dioxide (TiO2) Production and Manufacturing

07/11/2007· 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 generally has higher production costs and with acid treatment is more expensive to build than a
