magnetite (titanomagnetite) in terms of iron and vanadium recoveries as well as slag properties. The study was motivated by the desire to develop capacity to provide technical support to the minerals industry in the establishment and continuous optimization of industrial processes for the efficient extraction of Fe, V, and Ti from titanomagnetite.
The reducibility of titanomagnetite iron ore materials (agglomerate, pellets) with various TiO2 contents are studied. The mineralogical features of agglomerate and pellets before and after reduction are investigated. Calculations of technical and economic indicators of blast furnace smelting using iron ore materials with different TiO2 contents are carried out.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract

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)

A sodium modification–direct reduction coupled process was proposed for the simultaneous extraction of V and Fe from vanadium- bearing titanomagnetite. The sodium oxidation of vanadium oxides to water-soluble sodium vanadate and the transformation of iron oxides to metallic iron were accomplished in a single-step high-temperature process. The increase in
The comprehensive utilization of titanium-titanium magnetite began in the 1920s. When it was to meet the demand for vanadium and titanium, some countries represented by the Soviet Union, Norway, Finland, South Africa and Canada began to study vanadium-titanium magnetite. The problem of sorting and smelting has since opened the prelude to the comprehensive

In this paper, two processes for V-Ti magnetite smelting were introduced, the processes respectively are the conventional blast furnace-BOF process and the high-profile rotary hearth furnace direct reduction technology. The two kinds of processes were introduced briefly, and the problems of the two processes in the production of V-Ti magnetite were analysed.
Vanadium can be recovered from titaniferous magnetite ore by either of two processes: (1) precipitating a vanadium salt from a leach of ore roasted with salt, or (2) precipitation from a leach of salt-roasted vanadium-rich slag obtained by smelting the ore to make a vanadium-bearing pig iron, which is then blown in a
