Aug 03, 2020 Fluxless smelting of ilmenite to produce furnace slag as feedstock for the pigment industry is a well-established industrial practice with extensive installed smelting capacity globally.1,2,3,4 Commercial ilmenite smelters produce two products, namely titania-rich slag and a pig iron by-product. In contrast, smelting practices for titaniferous magnetite or titanomagnetite recover only iron ...
Oct 22, 2013 Ilmenite produced from the Panxi area in China has high impurities such as Ca and Mg. High-grade titanium Ti slag can be obtained by the electric arc furnace process, a traditional method of treating ilmenite. Thus, Ti slag prepared from the Panxi ilmenite contains high CaO and MgO, exceeding 5 pct of the slag content. This high CaO and MgO content confers considerable difficulty in ...

Titanium ore always involved in ilmenite and miners need to process the ilmenite to get high grade titanium materials in south africa. ilmenite nominally contains only 53 tio2, so it must be purified before further processing. raw ilmenite or slag ore is first soaked in sulfuric acid for several hours to free up the titanium from the.
In addition, the slag also contains approximately 10 FeO. Also present are impurities such as SiO2, Al2O3, MgO, MnO, CaO, Cr2O3, V2O5, and ZrO2. Due to the reducing conditions in ilmenite smelting, some of the impurities such as MnO are partially reduced, and report also to the metal phase.

In a process for producing titania slag from ilmenite, granular ilmenite first is partially reduced with a reducing agent in a reduction reactor, then the hot material with an inlet temperature of at least 550 C is transferred into an electric furnace and molten there in the presence of a reducing agent by forming liquid pig iron and titania slag.
Titanium slag. You can derive an extra benefit from titanium slag furnaces because they produce TiO 2 -rich slag and pig iron as valuable by-products. The ilmenite ore can be processed in either DC or AC furnaces. Its a special advantage of DC furnaces that they can smelt ore fines without pre-treatment.

Jul 23, 2021 Abstract The present communication describes an investigation on the preparation of metallized composite pellets from ilmenite concentrate. It was observed that the pellet size in the range of 812 mm, a binder dosage of 4 wt, and internal carbon of 5 wt are the optimum levels that help the pellets attain the desired drop number 10 and dry strength 30 kgpellet. When subjected to ...
The smelting of ilmenite to produce valuable titania slag and pig iron is an energy-intensive process. At process temperatures of about 1700 C, roughly 1 MWh of electricity per ton of ilmenite feed is consumed. Following successful laboratory-scale test work, a
Jul 12, 2021 Ilmenite smelting is a carbothermic reduction process used to upgrade the ilmenite mineral FeTiO 3 the process yields a TiO 2-rich slag as main product and pig iron as by-product.1 Such pyrometallurgical processes operate under high-intensity conditions, including high process temperatures, strong convection in the bath, and aggressive process materials e.g. TiO 2-rich
