Vanadium-titanium magnetite is a complex symbiotic iron ore resource composed of iron, vanadium, titanium and other metals, which is one of the most important iron ore resources in China [1,2,3,4].Titanium, as an indispensable metal raw material for the modern industry and advanced science and technology, is mostly derived from the vanadium-titanium magnetite …
The mineral composition of V-bearing shale ore is complex, and mica is the main V-bearing mineral followed by iron oxide (Li et al., 2022, Li et al., 2022; Zhou et al., 2022). V(III) …
Vanadium-bearing shale (VBS) is an important and unique vanadium resource besides vanadium-titanium magnetite in China, with an estimated reserve of approximately 62 billion tons (V 2 O 5) [1], [2].In recent years, vanadium extraction form VBS has been given continuous attention because of the increasing demand for vanadium products, especially the …
In this paper, the recovery of vanadium from the secondary tail deposits of iron ore by salt roasting-alkaline leaching and solvent extraction has been investigated. To extract the vanadium, after the characterizations studies (XRF, SEM, and EPMA analyzes), preliminary leaching was performed using HCl to reduce lime. Subsequently, the solid that was gained from this stage …
Vanadium-titanium magnetite, a multi-metallic ore rich in iron, titanium, vanadium, and various other metals, plays a pivotal role in high-quality steel production and …
The vanadium–iron spinel tightly interacts with iron olivine and glass equivalent . Roasting, ... Chu C. Study on separation of vanadium from low-grade resources containing vanadium. ... Liu H. Clean and cost-efficient preparation of vanadium electrolyte from the …
The reverse cationic flotation route widely used in the iron ore industry is less selective for alumina–hematite separation than for quartz–hematite separation. Pradip et al. (1993) studied the flotation of an alumina-rich Indian iron ore and reported that only 60% of the iron could be recovered in reducing the aluminum content from 11.6% ...
The invention discloses a method for separating and enriching vanadium from iron ore concentrate and producing pure iron, which comprises the following steps: and drying the vanadium titano-magnetite briquettes to obtain vanadium titano-magnetite pellets, directly reducing the vanadium titano-magnetite pellets by using a coal-based shaft furnace to obtain …
The KCJ offers high separation efficiency and has been evaluated for continuous operation and concentration of tin, beach sand, iron ore tailings and gold. More recently, a purpose built machine for iron ore industry, was first tested at IOC Canada in 1998 and IOC is considering the installation of a Kelsey jig beneficiation plant.
Moreover, conventional methods most frequently involve smelting and/or roasting as part of the separation process, releasing large quantities of CO 2 and other potentially harmful gases through combustion of the ore as well as the fossil fuels burned to power the whole affair; major gaps exist in many metals-refining markets for technologies ...
The total iron content was approximately 36.54%. But its Na 2 O and K 2 O content were relatively high in the tailings.
