Dec 31, 1970 . 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.
To obtained high titanium slag and so as to improve the comprehensive value of sea sand ore, we used smelting reduction technology and all vanadium-titanium magnetite iron ore in the experiments.. . In the process of experiments, the flow ability of slag was fine and the foaming slag was in control. The result of the.
Abstract. Experiments were carried out by adding CaF2 as catalyst in a Ar atmosphere to study the isothermal reduction kinetics of vanadium titano-magnetite carbon composite pellets under high temperature in the range from1473 to 1673K. By analyzing reduction mechanism, it was found that the rate controlling step was.
It is also recovered from wastes such as fly ash, oil residues and waste solutions from the processing of uranium ores. Nearly all of the world's vanadium is derived from mined ore as either direct mineral concentrates, usually vanadium- and titanium-rich magnetite, or as a by-product of steel-making slags. The United States.

High chromium vanadium–titanium magnetite has not been exploited and made full use of on a large scale so far due to the immature utilisation technology and the reality that the utilisation efficiency of valuable metals still urgently needs to be improved. In the present paper, the isothermal reduction kinetics and mechanism.
The influence of reduction temperature and gas composition on sticking behaviour of vanadium titano-magnetite oxidised pellets was investigated in this work. It was found that the sticking index (SI) increased with temperature and CO content of gas mixture. Microstructure transformation of sticking interfaces under different.

Abstract. The incorporation of contaminating elements in vanadiferous magnetite concentrates produced from layered intrusions can lead to expensive complications during vanadium extraction and purification processes. These contaminants may be contained in magnetites, as well as in gangue minerals attached to.
Mar 15, 2017 . TIVAN is a new process designed primarily for extracting vanadium, preferably as vanadium pentoxide, from a titano-magnetite ore body, (a geological igneous rock formation that contains significant quantities of iron, titanium and vanadium), and also for separating the titanium and iron preferably as ferric.
Jan 30, 2018 . The release rate of V from vanadium titano-magnetite was accelerated by light irradiation, and the oxidation of V was detected. . release of V is that the immobile low valence V is transformed to the mobile V(V) by photoinduced active species generated from the photocatalysis process of magnetite. Among.
