ABSTRACT. Adopting conventional sintering process of vanadium-titanium magnetite concentrates has such problems as low tumbler index and RDI due to the high As a multi-metallic iron-based ore, vanadium-titanium (V-Ti) magnetite has huge reserves in China, with a mineable grade of 9.83 billion tons (Li et al., 2018). A large amount of V-Ti magnetite tailings have been generated in the selection process of Fe concentrate, with an accumulated storage of about 570 million tons in the Panzhihua Multiple heavy metal distribution and microbial community

Blast furnace–basic oxygen furnace (BF–BOF) process is the predominant method for smelting vanadium titano-magnetite (VTM) in China. Hydrogen-rich (H2-rich) gas injection in BF is considered as an important way to reduce CO2 emission under the background of low carbon metallurgy. In this paper, the softening–melting behaviors of 1. vanadium-titanium magnetite ore. Magmatic vanadium-titanium magnetite ore is the main resource of titanium and vanadium in my country. The main useful minerals in the ore are titanomagnetite and ilmenite, which are mainly distributed in medium grains; gangues are mainly silicate minerals, and some also have carbonate minerals Three Types Of Vanadium Ore Beneficiation Methods

In this paper, potassium salt roasting additives were applied to extract vanadium from vanadium–titanium magnetite concentrate. Meanwhile, the mechanisms of potassium salt roasting and acid leaching kinetics were investigated. The results indicate that potassium salt roasting additives are more efficient than sodium and calcium salt Institute of Multipurpose Utilization of Mineral Resources, CAGS, Technology Innovation Center for Comprehensive Utilization of Strategic Minerals Resources, Ministry of Natural Resources, Chengdu, Sichuan, China. 摘要. 摘要: 这是一篇矿业工程领域的论文。. 本文综述了全球钒钛磁铁矿的分布状况以及目前其综合全球钒钛磁铁矿资源概况与综合利用研究进展

High-quality oxidized pellets are the basis to achieve high-efficiency utilization of vanadium–titanium magnetite (VTM) ores. Bentonite was used as a binder of VTM. The main phase composition of VTM is titanomagnetite and ilmenite. When the amount of bentonite is 1%, the compressive strength and dropping strength of VTM Vanadium-containing titanium magnetite is the main source of V and Ti in the internal market. About 75% Fe, 82% V, and 44% Ti pass into iron concentrate during ore enrichment [].Therefore, the question of how to improve comprehensive utilization of vanadium-titanium magnetite concentrate (VTMC) is of decisive importance for the High-Efficiency Extraction of Fe, V, and Ti from Vanadium
