The products includes five series: crusher, sand making machine, powder grinding mill, mineral processing equipment and building materials equipment.ilmenite processing pigments,The process naturally can be applied to high grade ilmenite. It bypasses electric furnace process which applies only to high grade ilmenite and is superior to the sulfuric acid process which is highly pollutant. The product of this process can be used to prepare the white pigment as well as titanium metal..
The main product of ilmenite processing is titanium dioxidewhich is used in a wide variety of industries and productssuch as paintspigmentsplasticsfoodcosmetics and pharmaceuticals. The mineral was first discovered in 1791 in Englandandcurrentlythe global production of titanium mineralscoming from ilmenite is dominated by
Ilmenite is an economically important and interesting mineral. It is named for its place of discovery (such places are called type localities) at Ilmen Lake in the Ilmen MountainsMiask in the southern portion of the Ural Mountains of Russia. Ilmenite forms as a primary mineral in mafic igneous rocks and is concentrated into layers by a process called magmatic segregation .
Nov 072007 TiO2 is produced from either ilmeniterutile 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 gradecheaper ores.
Sep 282020 Ilmenite occurs in black sand at the mouth of great rivers as in Indiaor as massive deposits like in Quebec Province in Canada. It is unsuitable for processing into pigment or for metal
Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3. Ilmenite is the primary ore of titaniuma metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxideTiO 2an important pigment
A process for producing titanium dioxide of a pigment grade from ilmenite in which ilmenite is optionally leashed with dilute hydrochloric acid to effect at least a substantial removal of the phosphorus content therefrom reacting the resulting ilmenite when in a particulate form with an excess of hydrochloric acid at an acid concentration greater than 25% ww to generate titanium ions in
Jan 012013 The two main commercial processes for producing titanium dioxide pigment are sulfate process (Barksdale1966) and chloride process (Winkler2003). The main feed stocks for these processes are high-TiO 2 slag andor synthetic rutile produced from ilmenite ore.
May 012019 Compared with processing high-TiO 2 concentrates such as ilmenite oresprocessing an anatase ore to achieve impurity levels acceptable for pigment production is more difficult because of the extensive number of accessory minerals presentthe significant intergrowths between minerals and the fact that impurity elements may be distributed in several different minerals.
Ilmenite can also be upgraded to synthetic rutile or titanium slagin the latter the TiO2 levels are increased to between 71% to 91%. Beneficiated feedstockssuch as titanium dioxide slagare especially sought for titanium dioxide pigment production via the chloride process. Recent years have seen a gradual transition towards the chloride
The present invention relates to silver-colored pigments comprising nonmetallic platelet-shaped synthetic substrates and at least one ilmenite-containing coating with an amount of iron compoundscalculated as elemental ironin the pigment of less than 5% by weightbased on the total weight of the pigmenta process for the preparation thereof as well as the use thereof.
A process for production of titanium oxide comprises digesting an ilmenite ore in which at least 92% by weight of the iron which is present is in the ferrous formif necessary adding a reducing agent and subsequently precipitating hydrous titanium oxide. When a reducing agent is added the amount used is equivalent to less than 4.0% by weight metallic iron calculated with respect to ilmenite ore.
Mineral sands are within a class of ore deposits that contain heavy minerals such as ilmenitezirconleucoxeneand rutile. The most importantnaturally occurring minerals that are mined to produce titanium dioxide (TiO 2) feedstock are ilmeniteleucoxene and rutile.The minerals are either used as feedstock in their natural form or in an upgraded formsuch as synthetic rutile and titania

principal white pigments used in paints were white leadzinc whiteand lithopone. In this method ilmenite was treated with concentrated H 2 SO 4 at 110120 C to form ferrous and titanyl sulfates: FeTiO 3 4H Fe2 TiO2 2H 2 O The reaction is conducted in large concrete tanks lined with acid
About 5% of the ilmenite mined is used to produce titanium metal. Some ilmenite is also used to produce synthetic rutilea form of titanium dioxide used to produce whitehighly reflective pigments. Most of the remaining ilmenite is used to make titanium dioxidean inertwhitehighly reflective material. The most important use of titanium dioxide is as a whiting.

A study has been carried out on the Becher and Summit Processes with the aim of understanding the mechanism and critical parameters required for the production of a range of pure iron oxide pigmentsas well as high quality synthetic rutile from reduced ilmenite. The Becher Process currently produces a large quantity of worthless mixed phase iron oxides.
