The Mineral Industry of Nigeria in 2012 - USGS Mineral Resources . Feb 12, 2014 sector. in late 2011, a study of the Nigerian mining sector was Cadastre Office, which is a department of the MMSD, processes .. secondary copper, diamond, emerald, garnet, ilmenite, refined or remelted lead, lime,.
process, is therefore one of the primary objectives of ilmenite smelting. Slag and iron are tapped periodically from separate sets of tapholes located around the circumference of the furnace. The slag tapholes are on a higher elevation than those for iron. Slag is tapped into 20 t steel pots, and cooled for
Roasting process. Ilmenite, as mined, has a high Cr 2 O 3 content which makes is unsuitable for direct smelting to titania slag. Some of this Cr 2 O 3 is removed at the mine when the ilmenite is passed through a magnetic separation step in which the highly susceptible Cr 2 O 3-rich fraction of the ilmenite .
The process is used in the USA, England, Japan, Taiwan, and Australia. Modifications for this technology were introduced as shown in Table 1. The process is not suitable for low-grade ilmenite because the silicate gangue will remain in the synthetic rutile thus decreasing its tenor in titanium.
Ilmenite mining process. Most ilmenite ore are poor ilmenite ore, so the ore processing must be carried out. Ilmenite ore beneficiation methods currently used for the mechanical selection (including washing, screening, re-election, high intensity magnetic separation and flotation), as well as fire enrichment, chemical processing method.

Selected recent innovations are then introduced towards more efficient cathode design and practices. Finally, the prospects of the FFC Cambridge process are discussed for processing the ilmenite ore and the so-called titanium-rich slag to produce Fe–Ti alloys .
Electro Smelting of Ilmenite for Production of Tio 2 Slag – Potential of India as a Global Player 827 in reduction of a portion of the Ti to Ti 2O3, which is less soluble in sulfuric acid and hence such slags are not suitable for the sulfate process pigment production.
The smelting process comprises the carbonaceous reduction of ilmenite to produce titania slag with a TiO2 content of 86%, and iron with a carbon content of 2.5%. In the Ti slag production process, the iron oxides are reduced to metallic iron, thereby producing a TiO2-rich slag and high purity iron.
pigment production through the chloride process. keywords: titanium slag, synthetic rutile, chloride process, sulfate process, acid leaching, TiO 2 pigment 1. Introduction Titanium is relatively abundant in the earth's crust, which is usually found in igneous and metamorphic rocks as ilmenite (FeTiO 3), rutile (TiO 2) and titanomagnetite (Fe 2
CHAPTER 2 ILMENITE SMELTING PROCESS OVERVIEW The purpose of this chapter is to introduce the reader to various aspects regarding the ilmenite smelting process. It also combines information from a number of literature resources to provide a consolidated body of data and information on which the work of this study is based.
In comparison with the conventional process of upgrading ilmenite, the process with leaching titanium slag in alkaline solutions requires relatively mild reaction conditions and high decomposition rate of titanium slag can be fulfilled under relatively low temperature and atmospheric pressure.
STUDY OF SODA EFFECT ON THE SINTERING PROCESS OF LOW TITANIUM SLAG Galymzhan Maldybayev1, Madali Naimanbaev2, Irina Shadrunova3, Nyna Lokhova2, Rustam Sharipov4 ABSTRACT The article presents study results of the sintering process of soda with low-titanium-containing slag, where the slag is produced during processing of titanium magnetite ...

Apr 26, 2015· In addition, the process has valuable by-products such as reduced ilmenite and pig iron, which are used as raw materials for the electric welding and special steel industry. Reduced ilmenite is also used in the sulphate TiO 2 manufacturing process. The titanium slag project started in early 2013.
Pilot-Scale Demonstration of Ilmenite Processing Technology UMD NRRI iii chloride leaching and solvent extraction system parameters for the ilmenite concentrate. The test program focused on the leach efficiency and extraction efficiency of the target elements; iron and titanium.
Unfortunately, Panzhihua ilmenite has a high calcium and magnesium content (Dong et al., 2012, Zhang et al., 2010, Zhang et al., 2011a), and the titanium slag produced from this ilmenite by the smelting process cannot be used as feed for the chloride process. This highlights the need to provide an effective method to further upgrade Panzhihua ...
Ilmenite from IREL, Chatrapur, Orissa and its thermally activated products such as metallised ilmenite and Titania rich slag were characterised to find out their suitability for the production of synthetic rutile (SR). [12] RRL Bhubaneswar has been working on thermal plasma processing of ilmenite.
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 ...

The Richards Bay slag was obtained by smelting a sand ilmenite. Material and Energy Balances. The ilmenite conversion process has been broken down into three general unit operations¬-reduction, smelting, and leaching—as shown in figures 8, 9, and 10.
Ilmenite ores can also be converted to liquid iron and a titanium rich slag using a smelting process. Ilmenite ore is used as a flux by steelmakers to line blast furnace hearth refractory. Ilmenite sand is also used as a sandblasting agent in the cleaning of diecasting dies. Ilmenite can be used to produce ferrotitanium via an aluminothermic
